China's PVC paste resin exports to Vietnam skyrocket in quantity   In recent times, the demand for PVC paste resin in Vietnam has experienced explosive growth. With a shortage of local production capacity and a high dependence on imports, the export volume of Chinese products to Vietnam has significantly increased.   Customs data shows that from January to April 2025, China's export volume of PVC paste resin to Vietnam was only 1100 tons; From January to April 2026, the export volume surged to 10000 tons, achieving a leapfrog growth in export scale. Currently, Vietnam is the core export destination for China's paste PVC resin.   It is reported that the downstream application scenarios of PVC paste resin in Vietnam are concentrated, and downstream demand is driving a wave of raw material procurement. Among them, synthetic leather and synthetic leather are the first consumer areas of polyvinyl chloride paste resin, mainly used in the production of shoe materials, home soft furnishings, and automotive interiors; Secondly, the floor leather and wall wallpaper are in line with the local infrastructure and home decoration market demand; The demand for medical PVC paste resin gloves, plastic toys, coated fabrics, drip molded products and other related fields is increasing synchronously, coupled with the continuous expansion of production capacity in Vietnam's domestic automotive and light industry manufacturing industries, resulting in a continuous widening of the raw material gap.   Relying on the tariff dividends of RCEP and the advantages of cost-effective products, domestic paste resin has become the preferred choice for Vietnam's procurement by replacing overseas sources. Currently, downstream factories in Vietnam maintain a low inventory and on-demand replenishment model, with stable support for raw material demand. Industry insiders indicate that with the steady development of Vietnam's light industry and auto parts industry, the import demand for paste PVC resin in the medium and long term remains strong, and China's export market to Vietnam will maintain a high level of operation.

In the production of soft PVC products, plasticizers are the core raw materials for regulating hardness, flexibility, and processing flow. The commonly available products on the market include general-purpose, environmentally friendly, and heat-resistant types, among others, with high-heat-resistant categories such as TOTM. The compatibility differences among these types are significant. Most workshops have long faced two major pain points: relying on experience for material allocation, leading to batch variations in hardness and softness; and arbitrarily adjusting plasticizer dosage to accommodate processing feel, which not only results in raw material cost waste but also easily causes issues such as plasticizer migration, oil bleeding, and substandard low-temperature and heat resistance performance. To achieve precise dosage and stable performance, it is not sufficient to rely solely on empirical formulas. A dual-verification approach of formula base data validation plus on-site measurement data review must be implemented, ensuring objective and evidence-based processes, with batch production only initiated after data compliance is confirmed.   1. Reference Basic Dosage of Plasticizers in Different Systems (Industry Measured Standard Data)   Based on 100 parts of PVC resin as a unified benchmark, within the conventional range of filler addition, after thousands of sets of production data statistics, precise dosage intervals are divided:   The standard dosage of conventional plasticizers for general soft products (ordinary sealing strips, general hoses) is 52-58 parts, and the mainstream value for conventional DOTP systems is 55 parts   High soft and cold resistant products (low-temperature hoses, outdoor soft accessories) require a standard dosage of 58-65 parts of cold resistant plasticizers. Production in low-temperature environments should prioritize approaching the upper limit   High heat resistant molded products (wire harness sheaths, high-temperature seals) with TOTM as the main heat-resistant plasticizer system: 48-55 parts, the higher the heat resistance requirement, the lower the overall reasonable dosage   Standard dosage of plasticizer for high filling economic products (general ordinary profiles): 45-52 parts. For every 10 parts increase in filling, the plasticizer is simultaneously reduced by 2-3 parts   Core conclusion: Under the same hardness requirements, the filling efficiency of heat-resistant plasticizers is higher, and the required amount of additives is lower than that of ordinary general-purpose plasticizers.   2、 First layer verification: Laboratory formula theoretical data verification   The hardness benchmark verification specifies the Shore hardness standard specified by the customer in advance. According to the basic ratio of small test strips, the hardness is tested after standing at room temperature for 24 hours. The error is controlled within ± 1A to be qualified. If it exceeds the range, the amount of plasticizer is fine tuned.   The verification of melt flow data detects the melt index of the material. Under the same production process, for every increase or decrease of 3 parts of plasticizer, the melt flow rate fluctuates within a fixed range to determine whether the dosage is suitable for the current extrusion and rolling equipment speed.   Basic compatibility verification: Static standing for 72 hours, observing the surface condition of the sample, no oil leakage, no whitening or delamination, proving that the current dosage matches the resin and additive system and is qualified.   3、 Second layer verification: secondary review of on-site production test data   The compliance of laboratory data is only the basis, and it must be verified again before entering the production line to prevent the disconnection between theory and on-site production:   Verify the fixed barrel temperature, screw speed, and melt pressure of the extrusion process status, observe the smoothness of the discharge, and ensure that the discharge is smooth without interruption or pressure build-up, representing that the amount of plasticizer is suitable for the current processing conditions; If the discharge is dry and the pressure is high, it should be moderately supplemented. If the discharge is too soft and sagging, it should be slightly reduced.   Real time physical property review of finished products: After mass production of 100 meters of finished products, 3 sets of samples are randomly selected for rapid on-site testing of bending toughness and shaping stiffness. If the sample data is consistent with the previous stage, it is considered qualified. If it is brittle and prone to breakage, it is confirmed that the amount of plasticizer used is insufficient; Soft to the touch and prone to deformation, confirm that the dosage exceeds the standard.   Long term stability data verification: Continuous production for 4 hours, with finished products sampled every hour to record hardness and appearance status data. The data shows no significant fluctuations, proving that the ratio can be used stably for a long time; Continuous data offset, adjust fixed usage in a timely manner.   4、 Objective laws for adjusting the dosage of plasticizers in different categories   Ordinary universal plasticizer: good flowability, high feeding tolerance, floating up and down by 3 parts, less likely to cause obvious quality problems, but long-term excessive use can easily lead to low-temperature precipitation   Environmentally friendly composite plasticizer: with balanced compatibility and a narrow dosage range, a fluctuation of 2 parts can significantly change the texture of the finished product, and strict data control is necessary   High heat resistant plasticizer: with stable molecular structure and high plasticizing efficiency, the dosage of ordinary plasticizers cannot be blindly copied. Blindly adding too much not only fails to improve performance, but also directly reduces the heat resistance and setting ability of the product   5、 Key points for strict control of dosage and avoiding pitfalls on site (repeatedly verified by data)   It is strictly prohibited to change the quantity arbitrarily based on the hand feel. All adjustments to the quantity must be based on hardness testing data and melting data   When replacing plasticizers of different brands and categories, the original fixed quantity cannot be used, and double-layer data verification must be conducted again   Synchronized review of seasonal temperature changes data, with high environmental temperatures in summer, the overall usage can be reduced by 1-2 servings; The winter temperature is relatively low, which can be adjusted up 1-2 times, and the data should meet the standard   When producing with recycled materials, the recycled materials come with residual plasticizers, and the residual content needs to be calculated in advance. At the same time, the number of newly added plasticizers should be reduced, and double verification should be carried out to avoid overall excessive usage   6、 Implementation effect of dual data verification   The batch error of finished product hardness is controlled within the smallest range in the industry, and the one-time pass rate of customer acceptance is greatly improved   Accurately locking in the optimal amount of additives can save 80-150 yuan in plasticizer raw material costs per ton of product   Avoiding common production defects such as precipitation, yellowing, brittle cracking, and inadequate heat resistance caused by imbalanced usage from the source   Unified and standardized data matching, even novice masters can accurately control production standards and break free from the constraints of old experience   Practical summary   Theoretical ratio is determined first, and hardness flow is verified first; Online mass production and retesting, with dual alignment of working conditions and physical properties; Different categories have different quantities, and the data should be accurate and not blindly followed; Double verification ensures stable ratio and improves quality while reducing costs.  

Introduction According to customs data, the import volume of PVC rensin in China decreased both year-on-year and month on month in April 2026, mainly due to loose domestic supply and demand. The monthly export volume has significantly declined, compounded by multiple negative factors, resulting in a reduction in monthly net exports.   Changes in import volume According to customs statistics, the domestic import volume in April 2026 has decreased and remains at a relatively low level. The reason for maintaining this low level is still due to the unchanged pattern of domestic Pvc Resin Suspension Grade supply exceeding demand, as well as low domestic and foreign demand. In addition, there are also reasons why domestic prices are lower than international prices. The import volume for the month was 16100 tons, a month on month decrease of 12.02% and a year-on-year decrease of 40.34%; The import amount was 11.5 million US dollars, a month on month decrease of 7.78% and a year-on-year decrease of 40.97%; The average import price was 715.36 US dollars per ton, an increase of 5.07% month on month and a decrease of 1.07% year-on-year. From January to April 2026, the import volume of PVC powder products was 56900 tons, a year-on-year decrease of 33.51%; The import amount was 40 million US dollars, a year-on-year decrease of 38.42%; The average import price was 703.04 yuan/ton, a year-on-year decrease of 7.38%.   Changes in export volume   In 2026, the export volume of PVC powder remained high, reaching a historic high in March, but the export volume declined significantly in April. According to customs statistics, the export volume of PVC powder in China experienced a significant decline in April 2026, mainly due to policy changes, declining demand, and increased export costs. The export volume of Pvc Suspension Resin during the month was 284700 tons, a month on month decrease of 58.38% and a year-on-year decrease of 20.96%; The export amount was 241.62 million US dollars, a month on month increase of 45.75% and a year-on-year increase of 5.55%; The average export price was 848.61 US dollars per ton, a month on month increase of 30.32% and a year-on-year increase of 33.55%. From January to April 2026, the export volume of Polyvinylchloride Resin products was 1.7016 million tons, a year-on-year increase of 27.32%; The export amount was 1111.37 million US dollars, a year-on-year increase of 30.10%; The average export price was 653.11 US dollars per ton, a year-on-year decrease of 2.19%.   Net export change   In April 2026, China's net export of PVC powder products was 268600 tons, an increase of 59.64% compared to the previous month, with a significant decrease in net export volume. The main reason for the significant decrease in net exports is the significant reduction in export volume, which is mainly due to the following reasons: 1. Policy changes directly overdraw previous demand Starting from April 1, 2026, the PVC export tax rebate policy will be officially cancelled in China. In March, enterprises concentrated on rushing to ship and overdrawn overseas orders in advance. The PVC export volume in March increased by 87.15% year-on-year to 800300 tons, leading to a rapid decline in subsequent export demand; 2. Global capacity expansion intensifies stock competition From 2021 to 2025, the global PVC production capacity has cumulatively increased by nearly 10% to 65 million tons, with the newly added capacity concentrated in Northeast Asia. The significant increase in overseas market supply has created substitution pressure on China's PVC exports. 3. The export cost advantage is gradually narrowing The geopolitical conflict in the Middle East has pushed up international shipping costs, with freight rates from China to core markets such as India doubling to over $100 per ton; At the same time, the overseas supply of ethylene based PVC is gradually recovering, and the price difference between domestic and foreign PVC has narrowed, weakening the price competitiveness of domestic products. 4. Increased uncertainty in overseas trade policies Major export markets such as India have launched anti subsidy investigations against Chinese PVC, and the preliminary ruling results are expected to be announced in June July 2026, further suppressing export intentions due to rising trade barriers.

Chrome green, a high-grade green pigment, has a density of 5.21 g/cm³ and a melting point of 2266°C. It resists high-temperature corrosion and exhibits stable resistance to hydrogen sulfide. Widely used in ceramic glazes, weather-resistant coatings, banknote inks, and organic catalysis, it combines high opacity with magnetic properties. However, toxicity must be guarded against, and storage requires sealing to prevent moisture.   Chrome green, also known as chromium(III) oxide (Cr₂O₃), is named after its light green crystalline form. It appears as a green hexagonal crystalline powder with a density of 5.21 g/cm³, a melting point of approximately 2266±25°C, and a boiling point as high as 4000°C. Chrome green is soluble in hot alkali metal bromate solutions but poorly soluble in water, alcohol, acids, and alkalis. This pigment exhibits exceptional stability against light, atmospheric exposure, high temperatures, and corrosive gases such as sulfur dioxide and hydrogen sulfide. Additionally, it possesses outstanding hiding power, though it is toxic. By boiling with sulfuric acid, chromium(III) sulfate can be obtained. When mixed and heated with the oxides of many divalent metals at high temperatures, spinel-type compounds can be formed. Chrome green can be prepared through various methods, including the reduction reaction of potassium dichromate with sulfur and the thermal decomposition of chromium trioxide. It is a high-grade green pigment with extensive applications in fields such as enamel and ceramic glaze production, coloring artificial leather and building materials, catalysis in organic synthesis, and the manufacture of weather-resistant coatings, grinding materials, green polishing pastes, and specialized printing ink for banknotes.   Basic properties of chrome green   Chromium green is a light green crystalline powder with a density of 5.21g/cm ³, a melting point of approximately 2266 ℃, and a boiling point of 4000 ℃. Difficult to dissolve in water, acid, or alkali, but soluble in hot alkali metal bromate solutions. As an advanced green pigment, chrome green not only has excellent coverage, but also exhibits extremely high stability to light, atmosphere, high temperature, as well as corrosive gases such as sulfur dioxide and hydrogen sulfide. This makes it widely used in various fields, such as enamel and ceramic glaze manufacturing, coloring of artificial leather and building materials, catalysis of organic synthesis, as well as the manufacturing of sun resistant coatings, grinding materials, green polishing pastes, and specialized printing ink for banknotes.   Stability and Storage of Chromium Green   Chromium green exhibits stability in light, atmosphere, high temperature, and corrosive gases, with high coverage and magnetism. Although it is stable to light, atmospheric conditions, and high temperatures, its potential toxicity should be monitored. Chromium green remains stable when used and stored according to specifications, does not decompose, and has no known hazardous reactions. It is insoluble in water, difficult to dissolve in acid, but soluble in hot alkali metal bromate solutions. Chromium green exhibits excellent stability against light, atmosphere, high temperatures, and corrosive gases such as sulfur dioxide and hydrogen sulfide. In addition, it also has high covering power and magnetism, but it should be noted that it will turn brown when heated and return to green after cooling. The standard enthalpy of formation is -1128.4kJ/mol, and the standard free energy of formation is -1046.8kJ/mol. The crystal structure of chromium green is similar to Al2O3, with hexagonal lattice parameters a=0.495nm and c=1.3665nm, and the density varies depending on the manufacturing method.   Chromium green should be stored in a ventilated, dry, and sealed environment to prevent moisture.   Application Fields   Lead chromium green plays a key role in the paint industry and is the main coloring pigment for green paints. In addition, it is widely used in the paint and plastic industries, and its application range is quite similar to that of lead chrome yellow. However, due to the presence of chrome yellow and lead in lead chromium green, attention should be paid to its potential toxicity when using it. Meanwhile, due to the presence of iron blue and oxidizing agent lead chromate, dust may spontaneously ignite when encountering Mars, so extra caution is required during the drying and crushing process. Once lead chromium green burns, its green pigment properties will be completely lost, transforming into a deep brownish yellow substance. In addition, when making nitrocellulose paint, in order to avoid the burning risk during rolling, the process of mixing lead chrome green after slurry grinding is usually adopted instead of rolling directly with lead chrome green.   Lead chromium green has also been applied in the metallurgical field, and it is an important component of ceramics, refractory materials, pigment industry raw materials, and organic synthesis catalysts. Lead chromium green can also be used as an analytical reagent and catalyst. Lead chromium green is used as a coloring agent in adhesives and sealants to improve their wear resistance and corrosion resistance.   In addition, lead chromium green can also be used for coloring enamel, ceramics, synthetic leather, and building materials. It can also be used as an organic chemical synthesis catalyst and sun resistant coating. Lead chromium green has applications in ceramics, refractory materials, adhesives, and cosmetics, but cannot be used in oral and lip cosmetics. Lead chromium green is also suitable for coloring cosmetics, especially eye cosmetics. However, it should be noted that it should not be used in oral and lip cosmetics, and facial cosmetics and nail polish are also not recommended.   Chromium trioxide is one of the key components of the silver plating immersion solution, and the newly prepared chromium trioxide can also be used to prepare important raw materials such as chromium fluoride and chromium bromide.

  Sodium Lauryl Sulfate（Or named Sodium dodecyl sulfate , SLS , K12） is an anionic surfactant, which is a white to pale yellow solid (can be divided into needle shaped or powder shaped), easily soluble in water, and has good compatibility with anions and non-ions. It has good emulsifying, foaming, penetrating, cleaning, and dispersing properties. Widely used in industries such as pharmaceuticals, papermaking, building materials, chemicals, textiles, oil extraction, cosmetics, detergents, toothpaste, shampoo, laundry detergent, plastic mold release lubrication, etc.   The function and use of sodium dodecyl sulfate: 1. It is mainly used as a foaming agent, cleaning agent, and moisturizing agent in cosmetics and skincare products (to make cosmetics come into contact with the skin as soon as possible and avoid being blocked by skin oils), which is relatively safe and does not cause acne; 2. Used as a detergent, textile bleaching aid, and carpet dyeing agent; 3. Wool detergent; 4. Leather softener; 5. Used as a foaming agent for toothpaste and fire extinguishers; 6.

Polyethylene Terephthalate (PET) are an important chemical product with excellent properties such as low cost, lightweight, high transparency, and recyclability, widely used in the packaging industry, primarily for containers like beverage bottles, food packaging, cosmetic bottles, and pharmaceutical bottles. In recent years, global PET bottle chip production capacity has continued to grow, while consumption has maintained a steady but slow upward trend. On a country-by-country basis, China remains the world's largest producer, consumer, and exporter of polyester bottle chips. Moreover, from 2024 onwards, China's new production capacity will account for approximately 79% of the global increase. Due to the ongoing expansion of China's Polyethylene Terephthalate bottle chip production capacity and the frequent anti-dumping incidents in the past, the future outlook for China's polyester bottle chip sector remains challenging. However, driven by the recovery of the global economy, there is still optimistic expectations for China's polyester bottle chip exports.   Basic Information on Polyester Bottle Chips Polyethylene Terephthalate bottle flakes are a synthetic polymer made by polymerizing and esterifying purified terephthalic acid (PTA) and ethylene glycol (MEG). PET resin have a uniform crystal structure, which helps to improve their physical strength and transparency. Due to their advantages of low cost, lightweight, high transparency, and recyclability, polyester bottle flakes are widely used in the packaging industry, mainly for containers such as beverage bottles, food packaging, cosmetic bottles, and pharmaceutical bottles.   Polyester bottle flakes are a product form of polyethylene terephthalate (PET), which is made into thin sheets through processing technology to obtain polyester bottle flakes. Polyester includes polyester fibers (polyester), polyester bottle sheets, and polyester films. In the domestic market, polyester fibers account for over 75% of polyester demand, including polyester filament and staple fibers, mainly used in the textile industry; Polyester bottle flakes account for about 20% of the demand for polyester, mainly used in bottle packaging and sheet materials. Among them, bottle packaging such as soft drink bottles and oil bottles account for about 70% of the demand for polyester bottle flakes, while sheet materials and other uses account for about 30%.   Supply and demand situation of global polyester bottle chip market   supply   From 2013 to 2023, the total global production capacity of Polyethylene Terephthalate Resin increased significantly, from 24.103 million tons to 34.565 million tons. During this period, the growth rate of production capacity was relatively fast from 2013 to 2015, with an average annual growth rate of 6.03%, and the increase mainly came from China, the Middle East, Africa, and South America. However, in 2016, the global economy was still undergoing a deep adjustment, with a slowdown in global economic growth and energy and chemical products basically in a bottom recovery period, resulting in negative growth in polyester bottle production capacity in 2016. From 2013 to 2023, the global utilization rate of bottle tablet production capacity remained at 77% -83%, indicating that although production capacity continues to expand, there has been little change in capacity utilization rate, and there has been no significant reduction or shutdown overall. Mainly because the global consumption of bottle flakes has been increasing, this trend supports the capacity utilization rate to remain at around 80%.   As of the end of November 2023, CCF data shows that the global production and consumption of polyester bottle flakes in 2023 are estimated to be 30.18 million tons and 31.76 million tons, respectively, with most of the excess consumption being accumulated inventory in early 2022. Compared with previous years, the global capacity utilization rate of bottle flakes in 2023 is 76.6%, which is at a relatively low level. The reason is that due to the impact of rising energy, transportation, and labor costs, the average capacity utilization rate in some overseas regions is low, especially in the European Union, where most facilities operate at low load for a long time, and the production of new capacity in the United States is delayed.   From the distribution of global Pet Resin Bottle Grade supply, in 2023, the global production capacity of polyester bottle chips is mainly concentrated in Asia, North America, and Europe, accounting for 57.8%, 15.1%, and 11.8% of the production capacity respectively. These three regions account for about 85% of the global production capacity. Asia has been the fastest-growing region in the polyester bottle chip industry in the past decade; The European and American regions are the traditional origins and production areas of polyester bottle chips. However, with the transformation of industrial patterns and consumption regions, there has been no significant increase in consumption. Therefore, there are not many new production capacity in the European and American regions, and some old production capacity is gradually being phased out. From the perspective of the distribution of polyester bottle chip production capacity among countries, the top four countries in terms of production capacity in 2022 are China, the United States, India, and South Korea, accounting for approximately 55% of global production capacity.   With the global production capacity of polyester bottle flakes increasing year by year, China's share of global production capacity is also continuously increasing, rising from around 27% in 2013 to around 38% in 2023. In 2023, the global production capacity of polyester bottle flakes will be concentrated in China, India, and Vietnam. In addition, in 2024 and beyond, the global new capacity is concentrated in China, Türkiye, Brunei and other places, and China's new capacity accounts for about 79% of the global new capacity.   consumption   Unlike the high growth rate of global polyester bottle production capacity, according to data, the global consumption of polyester bottle remains at a low growth rate. The global consumption of polyester bottle flakes in 2023 is mainly concentrated in China, North America, and Western Europe, accounting for 58% of the total global consumption. Specifically, in 2023, the consumption of polyester bottle flakes is mainly concentrated in mineral water bottles, carbonated beverage bottles, packaging, and film, accounting for 73% of the total consumption.   Unlike polyester fibers, the production capacity distribution of polyester bottle flakes is relatively dispersed, mainly influenced by population base, economic level, and consumption habits. Since 2012, the largest consumption of polyester bottle flakes worldwide has shifted from carbonated soft drink bottles to mineral water bottles, with mineral water bottles accounting for 35% of the total global consumption of polyester bottle flakes in 2023. This change is related to a shift in consumer attitudes, with a relatively rapid increase in consumption of packaged water and healthy beverages, while consumption of carbonated beverages has declined since reaching its peak in 2019.   trade flow   From the perspective of global trade flow of polyester bottle flakes, Asia is the main net export region, especially China, as the world's largest net export country, has shown a clear trend of rapid growth in export volume. Northeast Asia, South Asia, and Southeast Asia remain the net export regions of the Asian region.   In addition, North America was a net exporter before 2014, but has become a net importer since 2014, and the net import volume has been increasing year by year. The net inflow of polyester bottle flakes is mainly concentrated in the Americas, Europe, the Middle East, and Africa. In recent years, there has been a significant increase in net imports in the Americas, while net imports in Europe, the Middle East, and Africa have shown small-scale fluctuations.   In 2023, according to data, the Americas account for approximately 19% of global bottle tablet production capacity, mainly from the United States, and are also one of the main consumer regions for bottle tablets worldwide. Due to the high cost of polyester at the end of 2022, some bottle chip units in the Americas experienced production cuts, and downstream customers turned to purchasing imported goods. The import peak arrived earlier, but it was difficult for the United States and South American countries to quickly digest it in the short term, resulting in a decrease in import volume; With the peak consumption season in the later stage, supply and demand gradually improve. According to CCF's data, overall, the Americas' share of global imports will drop to around 26% in 2023. Europe is one of the main consumer regions for bottle flakes. Due to the lack of new production capacity in recent years, the global production capacity has declined to around 11%, and most facilities have experienced production cuts or shutdowns, resulting in high demand for bottle flake imports. Overall, Europe will account for about 36% of global imports in 2023, with a slight year-on-year increase，

Introduction   In April, the gross profit of PP Plastic Granules produced by different process routes in China mostly increased, among which the mainstream oil based, coal based, and PDH based PP saw varying degrees of increase in gross profit. Despite the relatively high prices of raw materials such as crude oil and propane, the overall PP spot price fluctuated at a high level in April, supported by tight market supply. The monthly average price increased by more than 10% month on month, driving a significant recovery in the gross profit of mainstream process PP. Among them, the gross profit of oil-based PP increased by 80.10% month on month, becoming the process route with the highest gross profit growth in April.   In April, the gross profit loss of oil to Polypropylene production enterprises decreased, with an average gross profit of -170.15 yuan/ton, an increase of 684.93 yuan/ton month on month, and an increase of 80.10%. Brent crude oil has increased month on month. According to data statistics, the monthly average price of Brent crude oil is $100.43/barrel, and the average cost of oil to PP production is 9513.99 yuan/ton, an increase of 209.40 yuan/ton or 2.25% month on month. During the month, the average price of oil to PP was 9343.84 yuan/ton, an increase of 894.32 yuan/ton or 10.58% compared to the previous month. The cost increase of oil-based PP is not as significant as the price increase, resulting in a decrease in gross profit losses for oil-based PP production enterprises.   The gross profit loss of oil-based Polypropylene in May may continue to decrease. At present, the Strait of Hormuz is still in a semi closed state with low traffic efficiency, and the United States has strict restrictions on Iran's oil exports, so the spot market is relatively scarce. Although Trump has been announcing smooth negotiations and constantly calming the market, from Iran's feedback, the differences between the two sides still exist, and the market is likely to have fluctuations, so oil prices continue to fluctuate. Overall, it is expected that the oil market prices will show a high and wide range of fluctuations, with a slight downward shift in the center of gravity. The cost of oil based Polypropylene may slightly decrease, but due to concentrated maintenance and significant supply side support, the price of PP is still supported. It is expected that the gross profit of oil based PP may slightly improve.   In April, the gross profit of coal to PP production enterprises increased, with an average gross profit of 2652.48 yuan/ton, an increase of 761.88 yuan/ton or 40.30% compared to the previous month. Thermal coal slightly increased compared to the previous month, and the average cost of coal to PP production was 6503.75 yuan/ton, an increase of 82.89 yuan/ton or 1.29% compared to March; The average price of coal made PP was 9156.23 yuan/ton, an increase of 844.77 yuan/ton or 10.16% compared to the previous period. The price increase of coal made PP was greater than the cost increase, resulting in an increase in gross profit of coal made PP.   The gross profit fluctuation of coal to PP Resin is expected to be limited in May. In May, downstream users will gradually release their demand for pre summer stocking to meet peak demand. Considering the current lower inventory levels of some power plants compared to the same period in previous years, the possibility of early high temperatures, and the limited cost-effectiveness advantage of imported coal, it is expected that downstream stocking procurement demand will significantly enhance market support and drive up coal prices. The cost support of coal to PP may be strengthened, but considering the strong support of PP prices, the gross profit of coal to PP is expected to remain stable with little change.   The gross profit of methanol to PP Granules production from external sources decreased month on month in April. The average gross profit of external methanol to PP production was 260.42 yuan/ton, a decrease of 365.57 yuan/ton compared to the previous period. The average price of methanol in April was 2632.92 yuan/ton, with a month on month increase of 435.15 yuan/ton, an increase of 19.80%. This led to a month on month increase of 1157.13 yuan/ton, an increase of 15.04%, in the cost of methanol to PP production. In April, the price of methanol to PP increased, with a month on month increase of 890.08 yuan/ton, an increase of 10.70%. The price increase of methanol to PP is not as significant as the cost increase of methanol to PP, resulting in a month on month decline in gross profit from external procurement of methanol to PP.   Looking at May, it is expected that the gross profit of external methanol to PP production may increase slightly. In May, the domestic methanol market may maintain an overall supply-demand balance, and the focus of transactions may be mainly on box oscillation. The import supply continues to shrink and there is a strong expectation of negative feedback from downstream products. Coupled with the inherent "spring inspection" plan of upstream and downstream factories in May, there is a multiple game of mentality and fundamentals. Overall, it is expected that the cost change of external methanol to PP production will be limited. Considering that PP price support is still relatively strong, gross profit may still increase slightly.   In April, the gross profit loss of PDH PP production enterprises decreased. The average gross profit of PDH PP was -1523.11 yuan/ton, an increase of 700.63 yuan/ton from the previous month, with a growth rate of 31.51%. The average cost of PDH PP production was 10845.64 yuan/ton, an increase of 220.14 yuan/ton or 2.07% compared to the previous period; The average price of PDH made PP was 9322.52 yuan/ton, an increase of 920.76 yuan/ton or 10.96% month on month. The price increase of PDH made PP was greater than the cost increase, resulting in a decrease in gross profit loss of PDH made PP.   It is expected that the gross profit loss of PDH PP will narrow in May. The import cost of propane in May remains high, and due to the impact of the Middle East situation, the amount of imported resources arriving at the port will also remain at a low level. Low supply remains an important supporting factor in the market. However, downstream demand is also expected to decline, and the PDH operating rate has dropped to a low level. The rise in temperature will also suppress the demand for combustion, and the market lacks sustained upward momentum. It is expected that the cost of PDH production of PP may slightly increase, and the supply of PP may be tight with high prices, resulting in a decrease in the extent of enterprise losses.   In April, the gross profit of PP production from external propylene procurement decreased, with an average profit level of -618.96 yuan/ton for the month, a month on month decrease of 88.39 yuan/ton, or 16.66%. The cost of producing PP from imported propylene in April increased by 942.02 yuan/ton compared to the previous month. The price of PP produced from imported propylene increased by 933.49 yuan/ton month on month. In absolute terms, the increase in cost of producing PP from imported propylene is greater than the increase in price of PP from imported propylene, resulting in an increase in gross profit loss.   The gross profit loss of PP production from imported propylene in May is expected to further expand. In May, there is still some support for the cost and supply side of the propylene market, and the overall demand side is stable but weakening. The propylene market is expected to have a supply-demand game, and there is a high probability of price fluctuations at a high level. Therefore, the cost of producing PP from imported propylene may still be high, and it is expected that the company's gross profit will suffer losses or expand.   Overall, it is expected that the gross profit of multi process PP in May will show a trend of first increasing and then decreasing. The current geopolitical situation still remains uncertain, with significant fluctuations on the cost side. The impact of geopolitical disturbances on the market is still ongoing, but over time, the market's response to news may gradually weaken. At the fundamental level, constrained by tight supply of raw materials, the pattern of industry equipment start-up and overall tight supply of goods will continue to support PP prices, driving a temporary increase in gross profit; As the shortage of raw materials gradually eases in the future, the industry's operating rate is expected to steadily rise, and the focus of PP prices may fall accordingly. The gross profit of PP in various process paths will also be under pressure and narrowed.

Customs statistics show that in the first quarter of this year, China's cumulative titanium dioxide exports reached approximately 536,800 tons, a year-on-year increase of 7.15%. Among this, March exports totaled 201,500 tons, marking a month-on-month growth of 33.03% and a year-on-year increase of 8.92%. Imports continued to decline, with the first quarter's cumulative imports amounting to about 15,600 tons, down 25.10% year-on-year.   In the first quarter, the export volume of chlorinated titanium dioxide rutile, which has higher technical content and added value, reached approximately 135,800 tons, marking a significant year-on-year increase of 39.24%. From January to February alone, chlorinated titanium dioxide exports amounted to 84,800 tons, rising by 45.21% year-on-year. Industry analysts noted that this indicates China's titanium dioxide sector is accelerating its transition from sulfuric acid-based scale expansion to high-quality development represented by the chlorination method, with continuous upgrades in the export product structure.   There are six reasons for the high export volume of White Powder Titanium Dioxide in China in the first quarter. Firstly, there is a mismatch in the timing of the Spring Festival. During the Spring Festival, the delivery of goods either shifts in pace or lags behind in orders, resulting in a clear emphasis on ensuring supply and competing for exports; The second is the initiation and resumption of anti-dumping investigations against Chinese titanium dioxide by countries such as the UK and India, with an increase in centralized replenishment and reserve orders before the tax increase; The third reason is that the situation in the Middle East has led to a shortage of energy for overseas producers. China's stable supply has taken on some orders, especially for chlorination products, which have low prices and good quality, and have gained recognition from more overseas users; Fourthly, compared with China, the demand for key industries such as real estate in most overseas countries is still steadily increasing, and the high volume of orders is also the norm; The fifth is the "de Americanization" adjustment of China's export market, shifting towards a significant increase in exports to ASEAN, Europe, Africa, and other regions, with more developing countries becoming key markets; The sixth is the explosion of overseas demand for new energy, photovoltaics, and other niche markets, which have been released to a certain extent. This is a rapid growth point for the high-end market. In summary, it is a combination of "short-term overvaluation" and "real growth". In fact, this is similar to the situation in China, where there is also a possibility of demand overdraft, which must be observed.   In the first quarter, the import and export of titanium dioxide pigment in China showed a pattern of "steady growth in exports, optimized structure, and continuous contraction in imports". The market achieved "stable quantity and price increase" under the push of costs, but we need to be cautious of weak demand foundation and external risks.   In the first quarter, especially in March, the price of titanium dioxide experienced a rapid increase. This is mainly due to the geopolitical conflict in the Middle East at the end of February, which led to a tightening of global sulfur supply and a continuous surge in sulfuric acid prices, thereby strongly pushing up the production cost of titanium dioxide. Leading enterprises have raised prices multiple times, and by the end of March, the average price of rutile titanium dioxide reached 15260 yuan/ton.   Since the beginning of this year, the industry has continued its trend of reducing production since 2025, with a slight year-on-year decrease of 2.8% in production in the first quarter and a capacity utilization rate of less than 70%. Before and after the Spring Festival, enterprise inventory remained low, providing support for price increases. In the first quarter, there was a demand for replenishment in overseas markets, and at the same time, it was affected by anti-dumping investigations in countries such as the UK and India, as well as production cuts by some overseas companies, which to some extent benefited China's titanium dioxide exports.   Despite the impressive first quarter data, market concerns cannot be ignored. One is that the demand foundation is not solid. This round of price increases is mainly driven by cost pressures, with limited improvement in actual demand in downstream industries such as coatings, plastics, rubber, papermaking ink, and chemical fibers. The sluggish domestic real estate industry has insufficient support for demand. The actual transaction situation of high priced orders in March was lower than expected. Secondly, exports are facing pressure. In the second quarter, India's early stocking effect may fade, coupled with rising trade barriers such as anti-dumping investigations, which may put pressure on the growth rate of traditional export markets. Meanwhile, the rising international shipping costs caused by the situation in the Middle East will continue to squeeze foreign trade profits. Thirdly, the industry faces significant profit pressure. Despite the increase in product prices, most enterprises are still operating at a loss or in an inverted state due to the greater increase in raw material costs, and the industry's profit pressure has not fundamentally eased.   Overall, the import and export data of titanium dioxide in the first quarter of this year reflects the industry's resilience under external shocks and positive progress in structural upgrading. However, the key to the healthy development of the industry in the future lies in whether it can break away from the simple cost driven model, consolidate the advantages of high-end products through technological upgrades, and effectively respond to changes in overseas trade environment and domestic demand challenges. Yu Jie analyzed and pointed out.   Judging from the cumulative decline in import volume in the first quarter of this year, according to this situation, the total import volume in 2026 is highly likely to drop to a new low. The export volume was basically not affected by the Spring Festival factor, among which the export of chlorination method increased significantly year-on-year, indicating that China's competitiveness is becoming stronger with the increase of chlorination method production capacity, quality improvement, and cost basically unaffected by raw materials.   The titanium dioxide market in the first quarter continued the sluggish trend of 2025, and the entire industry began to operate under negative pressure. After the Spring Festival, there were expectations of price increases, but the US Iran war accelerated this round of market. The closure of the Holms Strait pushed up oil prices, especially significantly reducing the import supply of sulfur. As a result, the titanium dioxide market experienced a rare continuous surge in the first quarter, with price increases exceeding the expectations of both upstream and downstream markets. There was also a linkage between domestic and international markets, with most manufacturers experiencing a situation of unsold products. Supply remained tight and is expected to continue for a period of time in the future.   The hot market has slightly improved the business situation of titanium dioxide manufacturers, but it should also be noted that the continuous price increase will lead to downstream terminal acceptance capacity changing from tight acceptance to numb waiting. After all, foreign manufacturers have lower price increases and slower pace, so we must be vigilant about the overdrawn impact of future price increases on future demand.

In March, the domestic titanium dioxide market witnessed an unprecedented price surge: Longbai Group Co., Ltd. issued three consecutive price increase notices on March 2, 16, and 24, raising domestic titanium dioxide product prices by a cumulative 2,000 yuan/ton, marking the highest monthly increase in recent years. Driven by leading companies, over 20 domestic titanium dioxide producers followed suit closely, creating a collective "three consecutive price hikes" trend. This sweeping price surge in the titanium dioxide market appeared to be a market-driven initiative by companies to adjust product prices, but in reality, it was a forced response to persistently rising upstream costs, further reflecting the structural adjustments in the domestic titanium dioxide industry under prolonged pressure.   Cost increases like a tidal wave，Raising prices is truly helpless   The rise in upstream raw material prices is the direct driving force behind the "three consecutive increases" of titanium dioxide white powder. The price increase behavior of titanium dioxide enterprises is essentially a helpless move under high costs, and it is also a survival defense battle of "no price increase, no loss".   In the production process of titanium dioxide powder, sulfuric acid is an indispensable core raw material, with a huge consumption and directly related to product costs. According to industry estimates, the production of titanium dioxide requires approximately 3-4 tons of sulfuric acid per ton, and every fluctuation in sulfuric acid prices is directly transmitted to the production cost of titanium dioxide. If the price of sulfuric acid rises by 500 yuan/ton, the cost of titanium dioxide will increase by 1500 yuan to 2000 yuan/ton. This cost increase is undoubtedly adding insult to injury for titanium dioxide companies that are already on the brink of losses. In March, the significant surge in sulfuric acid prices completely broke through the cost bottom line of titanium dioxide enterprises, becoming the direct trigger for the price increase of titanium dioxide.   The rise in sulfuric acid prices is rooted in the significant increase in upstream raw material sulfur prices, forming a cost transmission chain of "sulfur rise → sulfuric acid rise → titanium dioxide rise". According to commodity data platforms such as Shengyi Society, as of March 31, the domestic sulfur benchmark price reached 5726.67 yuan/ton, an increase of 46.46% from 3910 yuan/ton at the beginning of March. The price surge was fierce and fast, exceeding market expectations. The continuous rise in sulfur prices since 2026 is not accidental, but is driven by multiple factors such as geopolitical conflicts leading to supply tightening, concentrated release of spring plowing demand, and rising import costs.   The rapid rise in sulfur prices is transmitted downstream, directly driving a significant increase in sulfuric acid prices. As of March 31st, the benchmark price of sulfuric acid in China was 1580 yuan/ton, an increase of 49.41% from 1057.5 yuan/ton at the beginning of March.   Therefore, under the pressure of a significant increase in the prices of raw materials such as sulfur and sulfuric acid, the production costs of titanium dioxide enterprises have risen sharply, and the "internal driving force" for price increases is unprecedentedly strong. Price increases have become the only choice for enterprises to maintain normal production and alleviate cost pressures. As of March 31st, the ex factory prices including taxes for various types of titanium dioxide in China are as follows: sulfuric acid method gold red stone type is 14800 yuan to 15800 yuan/ton, anatase type is 14000 yuan to 14300 yuan/ton, and chloride method gold red stone type is 15000 yuan to 17500 yuan/ton.   Long term pressure on the industry, losses forcing price increases   The intensive price increases of titanium dioxide enterprises are not a substantial rebound in industry demand, but rather a long-term situation where the titanium dioxide industry is on the brink of losses and operating pressure continues to intensify, forcing enterprises to collectively raise prices in order to seek survival and breakthroughs.   In 2025, the overall performance of the domestic titanium dioxide industry will be sluggish, with market prices fluctuating downward, and companies generally facing the dilemma of "double decline" in revenue and profit, with some companies falling into losses. On March 24th, Anhui Annada Titanium Industry Co., Ltd., a well-established domestic titanium dioxide enterprise, disclosed its 2025 report, which showed that the company achieved a revenue of 1.69 billion yuan, a year-on-year decrease of 10.4%; The net profit attributable to the parent company was a loss of 92.58 million yuan, a year-on-year decrease of 922.5%. The performance forecast released by Guangdong Huiyun Titanium Industry Co., Ltd. shows that it is expected to lose 46 million to 65 million yuan in net profit attributable to the parent company in 2025. Jinpu Titanium Industry Co., Ltd. expects a net profit loss of 428 million to 489 million yuan attributable to the parent company in 2025.   The root cause of operational pressure for titanium dioxide enterprises lies in the two-way pressure of cost and price. In 2025, the domestic price of titanium dioxide will continue to fluctuate downward. According to data from Zhuochuang Information, the average price of titanium dioxide in China's market in the first half of 2025 will be 14425 yuan/ton, a decrease of 11% compared to the same period in 2024. Among them, the price of rutile titanium dioxide quickly fell from 15500 yuan/ton to 13700 yuan/ton in the second quarter. At the end of December 2025, the price range for domestic titanium dioxide rutile including taxes is between 12400 yuan and 13600 yuan/ton, and the price range for anatase titanium dioxide is between 11800 yuan and 12200 yuan/ton, both of which are at low prices in recent years. At the same time, upstream raw material prices continue to fluctuate, with core raw material prices such as titanium concentrate and sulfuric acid rising in turn, further compressing the profitability of enterprises. Data shows that from 2024 to 2026, the profitability of domestic titanium dioxide companies continued to deteriorate. After the third quarter of 2025, companies in the industry gradually entered a state of loss, and the losses further intensified in the fourth quarter, with a single ton loss of about 1800 yuan; In the first quarter of 2026 (as of March 25), the industry's losses further expanded, with single ton losses climbing to 2300 yuan/ton.   Although the price of titanium dioxide achieved three consecutive increases in March, with a cumulative increase of 2000 yuan/ton, this increase has not fully covered the upward pressure on the cost side. According to industry calculations, the increase in sulfur prices alone has brought a cost increase of over 1800 yuan/ton to titanium dioxide enterprises. The cumulative increase of three price increases can only barely cover this cost increase, and the improvement of enterprise profitability is limited. Most enterprises are still in a "low profit" or "break even" state.   The continuous operating losses are forcing the supply side of the titanium dioxide industry to accelerate its clearance, and the pace of industry reshuffle is constantly accelerating. According to statistics released by the Titanium Dioxide Industry Technology Innovation Strategic Alliance, by 2025, there will be a total of 18 enterprises in China's titanium dioxide industry with actual production of 100000 tons or more, an increase of 3 compared to 2024; Among the original production enterprises, 9 have stopped production or shut down, and 2 new enterprises (1 for hydrochloric acid method and 1 for chlorination method) have been added to production. On January 26th, Teno Group announced the permanent closure of its titanium dioxide production facility located in Fuzhou, Jiangxi Province, China. The factory has a production capacity of 50000 tons per year and has entered a long-term shutdown state since October 2025. The main reasons for the shutdown are weak domestic demand, overcapacity, and sustained low price levels. On the same day, Jinpu Titanium Industry Co., Ltd. announced that its wholly-owned subsidiary Xuzhou Titanium Dioxide Chemical Co., Ltd. had officially ceased production, further reducing the industry's supply. In addition, by 2025, China's titanium dioxide production will reach 4.72 million tons, a year-on-year decrease of 47000 tons, a decrease of 1%. This is the first time in over 20 years that China's annual titanium dioxide production has declined, which also confirms the acceleration of the industry's supply side clearance process.   Cautious optimism in the future, intensifying industry differentiation   The industry generally holds a cautious and optimistic attitude towards the future trend of the titanium dioxide market. In the short term, as the traditional peak season for consumption in the titanium dioxide industry, coupled with strong support from the cost side, the price of titanium dioxide is expected to maintain a high level. At present, the prices of sulfur and sulfuric acid are at a high level, and the possibility of a significant decline in the short term is low. The cost pressure on titanium dioxide enterprises will continue to exist.   Behind the optimistic expectations of the industry, there are still many hidden concerns, among which the uncertainty on the demand side has become a key variable affecting the subsequent price trend. With the arrival of the second quarter, the titanium dioxide industry will gradually enter the traditional off-season, and the demand for downstream end industries such as coatings and plastics will decline. Whether these industries can effectively bear the price increase will become the core factor determining whether the price of titanium dioxide can remain high. It is worth noting that the continuous price increase of titanium dioxide in March may overdraw some downstream demand. At present, terminal enterprises and distributor channels have completed phased stocking. At the same time, due to the faster upstream cost increase than the price increase of titanium dioxide, some titanium dioxide companies still face significant profit pressure.   In summary, the "three consecutive increases" in the titanium dioxide market in March were not a signal of industry recovery, but a passive response driven by costs, and more importantly, an active breakthrough for the titanium dioxide industry seeking survival after long-term losses. Against the backdrop of ongoing geopolitical risks and strong upstream cost support, titanium dioxide prices are expected to maintain a high volatility pattern in the short term. However, in the long run, the industry still needs to face deep-seated development issues such as weak demand, overcapacity, and profit pressure. This wave of price increases will further exacerbate the differentiation of the titanium dioxide industry: leading enterprises, with their advantages in scale, cost, and technology, are expected to gain a breathing space in this wave of price increases; However, due to the lack of economies of scale and weak cost control capabilities, small and medium-sized titanium dioxide enterprises will face the dual pressure of high costs and weak demand, which will further squeeze their survival space and accelerate the industry reshuffle process. This may be an important turning point for China's titanium dioxide industry to bid farewell to extensive growth and move towards high-quality development.  

The shadow of geopolitical conflicts is rapidly spreading to the commodities market. On the evening of March 8, international crude oil prices surged past the $100-per-barrel threshold for the first time in nearly four years, sending shockwaves through global markets and quickly triggering turbulence across the chemical industry supply chain. As a key downstream product of the oil industry, the PVA (polyvinyl alcohol) market has reacted accordingly. Reports indicate that Wanwei High-Tech (SH600063, stock price 7.07 yuan, market capitalization 14.629 billion yuan), a leading domestic PVA industry player, has issued a price adjustment notice. The company stated that due to rising raw material costs, it has decided to increase the prices of all PVA product varieties by 2,000 yuan per ton. The PVA industry leader announced a price hike across its entire product line .The reason for the price increase is the rise in the cost of upstream raw materials, with price adjustments following market trends. On March 9, a spokesperson from the Investor Relations Office of Wanwei High-Tech explained to reporters. However, the underlying reason is related to the rise in crude oil prices. As a fundamental chemical raw material, crude oil's price fluctuations are transmissive. Price adjustments are determined by upstream raw material suppliers. The upstream raw materials for PVA include vinyl acetate and ethylene, both of which are derived from crude oil. China is the world's largest PVA producer, with Wanwei High-Tech being a leading enterprise in the domestic PVA industry and one of the globally most productive PVA manufacturers. According to Wanwei High-Tech's 2025 interim report, PVA Resin, as a widely used polymer, is applied in various fields such as construction, textiles, new materials, and papermaking. The company has established four major industrial sectors: chemicals, chemical fibers, building materials, and new materials, along with five major industrial chains including VAC—PVA—PVA fiber, PVA—PVA optical film—polarizer, PVA—PVB resin—PVB film, biomass alcohol—ethylene—VAC—VAE/PVA, and VAC—VAE—re-dispersible powder. The company's interim report for 2025 revealed that during the reporting period, its PVA production reached 152,700 tons, marking a 33.17% year-on-year increase. Sales revenue amounted to 1.333 billion yuan, rising by 24.58% year-on-year. This translates to a PVA selling price of 8,730 yuan per ton. Meanwhile, data indicates PVA supply shortages, with the market average price standing at 10,076 yuan per ton.   The U.S.-Iran conflict continues, with over half of chemical product prices rising accordingly. As a bulk commodity closely tied to oil, PVA prices are highly correlated with crude oil trends. According to Xinhua News Agency, influenced by the ongoing military conflicts between the U.S., Israel, and Iran, international crude oil futures prices broke through $100 per barrel on March 8, marking the first time since mid-2022. Data showed that the futures price of light crude oil (WTI) for April delivery at the New York Mercantile Exchange surged to $111.24 per barrel, a 22.38% increase. It is reported that due to the war blocking the passage of the Strait of Hormuz, major oil-producing countries such as Iraq, Kuwait, and the UAE were forced to reduce production because of insufficient oil storage capacity, further exacerbating the supply shortage. The ongoing U.S.-Iran geopolitical tensions are one of the primary drivers behind the recent surge in chemical product prices. According to a research report released on March 8, during the first week of March (February 2 to February 6), 195 out of the 336 chemical products tracked by the report experienced price increases, accounting for 58% of the total. As the U.S.-Iran tensions continue to escalate, disruptions in crude oil supply and transportation have affected multiple countries, leading to sustained price hikes in chemical products. In addition to PVA, price increases have been observed across multiple categories such as chromium chemicals, polyurethane, amino acids, and dyes. This indicates that cost pressures triggered by oil prices are spreading widely within the chemical industry. The sharp fluctuations in crude oil prices have cast an uncertain shadow over the trends in commodity prices. How will oil prices evolve in the future? China imports approximately 20% of its crude oil from the Middle East and maintains a relatively robust strategic oil reserve. By releasing our strategic oil reserves to counteract the supply-side shock, we are less affected compared to Japan and South Korea, so there's no need to be overly pessimistic.

1.What exactly are they "what things"?    1)  Calcium carbonate: CaCO₃, essentially an ionic crystalline mineral with a regular structure and high    hardness, but inherently poor compatibility with organic polymers.    2)  Silicon dioxide: SiO ₂, mainly amorphous (such as white carbon black), with a strong covalent network structure. The surface is rich in silicon hydroxyl groups, with a large specific surface area and high activity.   3)  Talc powder: Mg₃Si ₄ O ₁₀ (OH) ₂, is a layered silicate with plate-like crystals, possessing a natural lubricating sensation and a certain degree of rigidity.  4)  Kaolin: Al ₂ Si ₂ O ₅ (OH) ₄, is also a layered silicate, but its structure and surface chemical properties are different from talc powder, usually with better electrical insulation and chemical inertness.   From the structure, it can be seen that they have several crucial differences: ① Calcium carbonate is the least polymer like substance It is a typical hard and brittle inorganic particle, and the interface bonding force between it and the polymer matrix mainly relies on physical adsorption and limited surface treatment, with weak intrinsic affinity. ② Silicon dioxide is one of the fillers with the strongest surface interactions Especially for precipitated white carbon black, the surface is entirely composed of hydroxyl groups, which can generate strong physical adsorption and even hydrogen bonding networks with chain segments. It can easily affect the rheological and mechanical behavior of polymer systems ③ Talc powder and kaolin are essentially fillers with a "sheet-like structure" This form gives them anisotropy and can form physical barriers in the matrix, restricting the movement of molecular chains. Therefore, it is more efficient in improving rigidity, dimensional stability, and barrier performance.   From the perspective of polymer physics, the role of fillers can be summarized as follows: 1). Limit segment movement (affecting Tg, modulus, creep) 2). Change stress transmission and distribution (affecting strength and toughness) 3). Affects crystallization behavior and processing rheology (nucleation, viscosity, shrinkage) Different forms of fillers (spherical, sheet-like, high specific surface area amorphous) have vastly different mechanisms and effects in achieving these effects.   2. If you only want to "reduce costs" - then choose calcium carbonate If your first goal is to reduce costs,Calcium carbonate must be the first choice. Because the essence of calcium carbonate is: Raw material: Limestone, with a wide reserve. Process: Grinding/grading/surface treatment is relatively simple and mature. Unit volume price: Almost the lowest among all inorganic fillers. From an engineering perspective, the greatest value of calcium carbonate is in one sentence: it is a "volume filler", not a "performance modifier". The main effects it can bring include significantly reducing the cost of raw materials for products. To some extent, improve the rigidity and modulus of composite materials. Reduce shrinkage and improve dimensional stability. Improve processing performance (such as fluidity) in certain systems. But you should also be aware that its help in strength, toughness, heat resistance, and long-term reliability is very limited, and often even negative. From a microscopic perspective, the reason is also very simple: there is basically no interaction between calcium carbonate particles and polymer chains. Essentially, it is the "stone powder buried in the resin matrix" that is prone to debonding at the interface, becoming a crack source, and premature failure when subjected to stress. Therefore, the experience is that calcium carbonate is a cost oriented filler. Suitable for daily necessities, disposable products, non structural components, and large quantities of low-priced products with low requirements for mechanical performance and long-term reliability Not suitable for: any structural components or critical parts with clear requirements for strength, toughness, or durability   3.When you start pursuing 'performance', you must look at the other three   If your goal changes from 'as long as it works' to' this thing needs to be stable, reliable, and have structural strength 'Then calcium carbonate will automatically exit the main stage.   At this point, you need to consider Silicon Dioxide Powder, talc powder, and kaolin.   ① Silicon dioxide: When you want to "strengthen" and "control rheology" Its typical application scenarios are highly concentrated in: reinforcing adhesives for rubber products (such as tires and shoe soles), thixotropy of sealants, anti sagging coatings, anti settling of inks, and thickening of silica (especially high specific surface area white carbon black) The most unique thing is that it is not simply filled in, but rather 'building a network within the system' From a microscopic perspective, a large number of hydroxyl groups on the surface can form strong adsorption with polymer chains and even form hydrogen bonding networks between themselves, resulting in a significant increase in the modulus (especially tensile stress) of composite materials. The viscosity of the system increases sharply, resulting in significant shear thinning behavior (thixotropy). The interface bonding of dispersed phases is strong, which facilitates stress transmission. So you will find that any system that needs to "stand, not collapse, and not flow" often uses silica.   ② Talc powder: When you want "rigidity+dimensional stability+heat resistance" The core value of talcum powder lies not in its chemical composition, but in its sheet-like structure, which brings three very important engineering effects: limiting chain segment deformation like a small steel plate, strongly suppressing thermal shrinkage, and significantly increasing bending modulus and thermal deformation temperature. Therefore, in PP automotive interiors and structural components with high dimensional stability requirements for home appliance shells, talcum powder is almost the preferred or standard filler From a microscopic perspective, talc powder is essentially an inorganic layer that serves as a framework for polymers.   ③ Kaolin: When you pay attention to "electrical properties, barrier properties, system stability" Compared to talc powder, kaolin has better electrical insulation, higher purity, fewer ionic impurities, and higher volume resistivity. Good barrier properties: The layered structure is regular and can extend the permeation path of gases and liquids. Stronger chemical inertness: With lower surface acidity, it has less impact on the curing or aging process of certain systems such as adhesives and rubber. So it is commonly used as a functional filler for wire and cable insulation materials, rubber products (such as tire tires, rubber hoses), certain high-performance coatings and sealants, and plastic barrier films. Structurally, it is also a sheet-like silicate, but more functional filler rather than cheap reinforcement.   4.The true engineering logic is not 'who to choose', but 'what you want' In the end, you will find that there is no "best" filler, only the one that best meets the goal. You can follow this logic and ask yourself: What I want is: Cost? → Calcium carbonate, Strengthening or controlling flow? → Silicon dioxide, Rigid+Dimensional Stability? → Talc powder, Insulation/Barrier/Stability? → Kaolin   When selecting materials, we need to think more: fillers are not "added", but "participate in the construction of the system structure". Its introduction directly determines the mobility of molecular chains (glass transition, relaxation behavior) The transmission and dissipation mechanism of external forces (strength, toughness, fracture behavior) The initiation and propagation path of defects (fatigue, durability) The permeation and diffusion process (aging) of environmental media (water, oxygen) Understanding their essential differences and capability boundaries is the key to not being a blind trial and error maker when designing formulas, but rather a clear minded architect.

According to statistics released by the Secretariat of the Titanium Dioxide Industry Technology Innovation Strategic Alliance on January 10, China's total titanium dioxide production in 2025 reached 4.72 million tons, a decrease of 47,000 tons or 1.0% year-on-year. This marks the first decline in annual titanium dioxide production in over 20 years.   In 2025, there will be 36 fully integrated titanium dioxide production enterprises with normal production conditions across the entire industry (excluding those that solely purchase crude products for further processing or post-treatment), a decrease of 9 compared to the previous year.   In 2025, the production of rutile titanium dioxide will reach 4.103 million tons, accounting for 86.9% of the total output; The amount of rutile titanium dioxide is 503000 tons, accounting for 10.7%; Non pigment grade and other types of titanium dioxide account for 115000 tons, accounting for 2.4%. Among them, the production of chlorinated titanium dioxide was 752000 tons, an increase of 89000 tons from the previous year, accounting for 15.9%, and 18.3% of the production of rutile titanium dioxide.   By 2025, there will be a total of 18 enterprises in the national titanium dioxide industry with actual production of 100000 tons or more, an increase of 3 compared to the previous year. At that time, 9 of the original manufacturers stopped production or closed down, but 2 new enterprises (one for hydrochloric acid titanium dioxide and one for chloride titanium dioxide) were added to production.   According to statistical data, by 2025, the effective production capacity of the entire titanium dioxide industry will be 5.7 million tons per year, with an average capacity utilization rate of 82.8%, which is at a medium to low level. However, if calculated based on a comprehensive production capacity of 6.1 million tons per year (including production capacity that has been shut down or partially shut down), the capacity utilization rate is 77.3%. This data indicates that the capacity utilization rate of the titanium dioxide industry in China is at a relatively low level, with severe oversupply of capacity.   According to customs data statistics, a total of approximately 1.8169 million tons of titanium dioxide pigment were exported from January to December 2025, a year-on-year decrease of 4.46% or approximately 84800 tons. The annual export volume of titanium dioxide has experienced its first decline since 2016. Among them, the export of chlorinated titanium dioxide was 366500 tons, a year-on-year increase of 5.95%; The export of sulfuric acid titanium dioxide was 1.4505 million tons, a year-on-year decrease of 6.77%;

  Misconception One: The higher the titanium content in titanium dioxide, the higher the whiteness?   Truth: Whiteness is a comprehensive indicator, not determined solely by titanium content.   Titanium content is one of the influencing factors, but impurity control, particle size, and surface treatment are equally crucial. Titanium dioxide achieves higher whiteness and coverage efficiency in downstream application scenarios through different refined process controls based on reasonable titanium content, avoiding cost waste caused by blindly pursuing high content.   Misconception 2: Does titanium dioxide make paper fragile and reduce paper quality?   Truth: Paper strength is influenced by multiple factors, not just titanium dioxide.   Because using White Powder Titanium Dioxide as a filler will occupy the fiber bonding space, which to some extent affects the strength of the paper, but other factors such as the dispersion uniformity of the filler, fiber state, and drying process have a more significant impact. Therefore, the key lies in selecting titanium dioxide with good dispersibility, controlling the addition amount reasonably, and matching suitable processes, so as to improve the optical properties of the paper while maintaining its physical strength and toughness, and achieve the optimization of comprehensive quality.   Misconception 3: Will titanium dioxide react with the components in paper to produce harmful substances?   Truth: Titanium dioxide has stable chemical properties, and its safety depends on purity and compliance.   Titanium Dioxide Pigment has extremely stable and inert chemical properties, and will not undergo harmful chemical reactions with cellulose, other fillers, chemical additives, etc. in paper. The key is to select high-quality titanium dioxide that meets relevant safety regulations and ensure that its application process complies with specifications. Titanium dioxide strictly adheres to product safety and compliance standards, never introduces harmful substances, and can be safely used in the production of various paper products.   Misconception 4: The more titanium dioxide used, the higher the opacity?   Truth: There is indeed an increase, but it follows a diminishing marginal effect.   Initial addition can significantly improve opacity, but excessive addition slows down the effect growth, increases costs, and affects paper performance. Within a reasonable range of additions, we help customers achieve their target opacity with low usage through the high coverage of our products, achieving cost reduction and efficiency improvement.   Misconception 5: Can titanium dioxide cause decorative paper to turn gray after being pressed and exposed?   Truth: High quality titanium dioxide is actually the key to anti graying.   The paper exposure gray change is closely related to the dispersion uniformity, impurity content, and surface treatment of titanium dioxide. Adding high-quality, well surface treated (such as inorganic and organic coating) rutile titanium dioxide not only does not cause the decorative base paper to turn gray after being pressed and exposed, but is also a key component in resisting gray transformation, ensuring paper whiteness and coverage. Titanium dioxide BLR-852 adopts rutile crystal structure and special coating process, with good dispersibility, low impurities, high retention rate, and high blue wool index, which can effectively maintain paper whiteness and cover stability, avoiding the phenomenon of gray transformation after the original paper is pressed and exposed.   Summary: Choosing the right titanium dioxide results in better paper quality   In the papermaking process, there is no "unique standard", only the "most suitable combination".   If you are looking for a titanium dioxide solution for papermaking that balances performance and cost, please feel free to contact us at any time.

On December 5, 2025, the Central Board of Indirect Taxes and Customs (CBIC) of India issued Customs Directive No. 33/2025, instructing all local authorities to immediately cease the imposition of anti-dumping duties on titanium dioxide (titanium dioxide) originating from or exported from China.   This decision stems from the ruling of the Kolkata High Court on September 22, 2025, which found significant flaws in the Indian government's previous anti-dumping investigation procedures and therefore revoked the tax notice issued on May 10, 2025.   This means that with a directive from the Indian customs department, the heavy anti-dumping duty of $460-681 per ton on Chinese titanium dioxide companies in the Indian market has been lifted, and this market, which accounts for 10% of China's total titanium dioxide exports, has reopened its doors to Chinese companies.   This trade dispute began on March 28, 2024, when the Indian Ministry of Commerce and Industry officially launched an anti-dumping investigation into titanium dioxide from China.   After nearly a year of investigation, the Indian Ministry of Commerce and Industry made a positive final ruling on February 12, 2025, recommending the imposition of anti-dumping duties on Chinese Titanium Dioxide Pigment.   On May 10, 2025, the Revenue Department of the Indian Ministry of Finance issued a notice accepting the final ruling recommendation of the Ministry of Commerce and Industry, deciding to impose anti-dumping duties of $460-681 per ton on titanium dioxide originating from or imported from China, with a validity period of 5 years.   However, this decision was opposed by the Indian Coatings Association, which filed a lawsuit with the Kolkata High Court. On September 22, 2025, the court made a ruling to cancel the government's decision to impose anti-dumping duties on imported titanium dioxide from China and sent the case back to the General Administration of Trade Remedies for re examination.   The Indian market is crucial for the Chinese titanium dioxide industry. As one of the top ten importers of titanium dioxide in China, India holds an important position in the export market of titanium dioxide from China. The core of India's demand for titanium dioxide comes from the urgent needs in the fields of coatings, plastics, and other industries driven by industrial and infrastructure development. Its local production capacity is far from matching market demand, and high-performance products such as high-end rutile are difficult to produce independently. Therefore, it is highly dependent on imports, with more than 60% relying on imports to fill the gap. Chinese sources have become the main supply choice due to their cost-effectiveness.   In 2024, the total import value of the top ten countries of origin for Indian titanium dioxide reached 1.135 billion US dollars, a year-on-year increase of 22.62%, with China leading with 666 million US dollars (a year-on-year increase of 25.2%); However, from January to November 2025, the total import value of the top ten countries decreased to 837 million US dollars, a year-on-year decrease of 20.47%. China's import value also fell back to 507 million US dollars (a year-on-year decrease of 17.53%), while Canada and Singapore's import value increased by 80.16% and 1103.16% respectively, reflecting the contraction of India's titanium dioxide import scale and the diversification of supply sources.   Affected by anti-dumping policies in major markets such as India and Brazil, China's titanium dioxide exports in the first half of 2025 will face the "three lows" dilemma - a comprehensive decline in export volume, export average price, and year-on-year growth rate. In October 2025, China's titanium dioxide exports were 146400 tons, a decrease of 6.33% month on month and 5.12% year-on-year. The cumulative export volume from January to October decreased by 101400 tons compared to the same period last year. The main reason for the decline in export volume is that multiple major export markets have imposed high anti-dumping duties on Chinese titanium dioxide, which has become the biggest obstacle to titanium dioxide exports in recent times, and export orders continue to shrink. With India lifting its anti-dumping duties on titanium dioxide from China, Chinese titanium dioxide companies will regain multiple competitive advantages in this market.   The elimination of tariff barriers has restored the price competitiveness of Chinese titanium dioxide in the Indian market. According to industry analysis, stopping the imposition of anti-dumping duties will significantly reduce the import cost of Chinese made White Powder Titanium Dioxide.   For Indian paint companies, this means obtaining short-term cost relief. In the case of relatively stable demand, an increase in supply may exert downward pressure on the spot price of titanium dioxide.   Chinese titanium dioxide companies are expected to regain lost market share. During the implementation of anti-dumping duties in India, the import sources of Titanium Dioxide White in India showed a diversified adjustment, and the import volume of countries such as Canada and Singapore increased significantly. With the elimination of tariff barriers, China's position as a traditional major supplier is expected to be restored.   The complete supply chain and stable production capacity of China's titanium dioxide industry are also important advantages. Compared to other supply countries that require long-distance transportation, China has a closer geographical location, lower logistics costs, and shorter delivery cycles.

Misconception 1   Real titanium dioxide floats on the surface of the water, fake products sink to the bottom?   Truth: Whether titanium dioxide floats on the water surface does not represent the authenticity of titanium dioxide.   To meet the low water content requirements of titanium dioxide in the plastic field, manufacturers will use silicone oil, silane, or siloxane to hydrophobize titanium dioxide, which will float on the water surface; The titanium dioxide treated with TMP exhibits hydrophilicity and sinks to the bottom of the water, but it is still genuine titanium dioxide.   Misconception  2   Titanium dioxide is a 2B carcinogen, and plastic products containing titanium dioxide can be harmful to health   Truth: Plastic products made with compliant titanium dioxide produced by legitimate manufacturers will not harm human health.   Titanium dioxide in plastic processing needs to withstand high temperatures (200 ℃) and have a stable coating. There is no evidence to suggest that compliant products will migrate toxic substances. In August 2025, the European Court of Justice (ECJ) made a final ruling, rejecting the appeals of the French government and the European Commission, and upholding the judgment of the EU General Court - officially revoking the carcinogenic classification of some powdered titanium dioxide (TiO2) and banning titanium dioxide in the EU; The US FDA still allows its use in food packaging plastics (such as microwave lunch boxes).   Misconception  3   The more titanium dioxide added, the whiter the furniture shell becomes   Truth: The whiteness of plastic products is not strictly proportional to the amount of titanium dioxide added.   Within a certain range, as the amount of titanium dioxide added increases, the whiteness will improve. But when the addition amount exceeds a certain critical value, the whiteness may no longer increase significantly, and may even lead to a decrease in other performance. In addition, with the same amount of titanium dioxide added, the particle size, impurity element content, and particle morphology of titanium dioxide can also affect the whiteness of the product.   Misconception  4   Titanium dioxide used for plastics contains heavy metals, which can pollute the environment and harm human health.   Truth: The heavy metal content in titanium dioxide used for compliant plastics produced by legitimate manufacturers meets relevant safety standards.   Plastic grade titanium dioxide produced by legitimate manufacturers must pass heavy metal testing (such as lead, arsenic, mercury, etc.) and comply with SGS or FDA standards. It has stable chemical properties, is insoluble in water, acid, and alkali, does not decompose or migrate in the environment, and does not pollute the environment or harm human health.  

Polyvinyl alcohol (PVA, also known as PVOH ) is a water-soluble polymer obtained by polymerization and alcoholysis of vinyl acetate (VAc). It appears as a white sheet-like, granular or powdery solid (low alkali alcoholysis process) or a white flocculent solid (high alkali alcoholysis process). According to the different raw materials, the production process of polyvinyl alcohol is mainly divided into two ways: one is the ethylene route, which is petroleum ethylene or bioethylene vinyl acetate polyvinyl alcohol; Another type is the acetylene route, which involves natural gas acetylene or calcium carbide acetylene vinyl acetate polyvinyl alcohol. The process characteristics of the petroleum ethylene route are that the production scale is larger than that of the acetylene method, the product quality is good, the equipment is easy to maintain, manage and clean, the heat utilization rate is high, the energy savings are significant, and the production cost is more than 30% lower than that of the acetylene method. The disadvantage is that the catalyst uses palladium as the active component, which is relatively expensive; The process characteristics of the calcium carbide acetylene route are relatively simple operation, high yield, easy separation of by-products, but high energy consumption, relatively poor product quality, high production costs, and the waste generated can easily cause environmental pollution. At present, most foreign polyvinyl alcohol producers such as Japan and the United States use the petroleum ethylene process for production, while China mainly uses the acetylene process for production.   Production status The production of polyvinyl alcohol in China began in the 1960s. In 1965, a thousand ton production facility was built in Siping, Jilin. In the same year, Sinopec Beijing Dongfang Petrochemical Organic Chemical Plant (formerly known as Beijing Organic Chemical Plant) introduced technology from Japan to build China's first 10000 ton calcium carbide acetylene method (changed from calcium carbide acetylene method to petroleum ethylene method in 1995) production facility; In the 1970s, 9 sets of 10000 ton production facilities were built in various parts of China, all of which adopted the calcium carbide acetylene production process. In the 1980s, through technology introduction, the petroleum ethylene production unit of Sinopec Shanghai Petrochemical Co., Ltd. and the natural gas acetylene production unit of Sinopec Chongqing Chuanwei Chemical Co., Ltd. (formerly Sinopec Sichuan Vinylon Plant) were respectively built and put into operation. Since then, the production capacity of polyvinyl alcohol in China has steadily increased, reaching 1.451 million tons per year in 2016. Subsequently, due to environmental impacts, poor business performance, or changes in production, not only were no new or expanded facilities built and put into operation, but multiple production facilities were also shut down one after another. In 2024, Anhui Wanwei High tech Materials Co., Ltd. will complete and put into operation a 60000 ton/year new plant, while the existing plant will be shut down. As of the end of December 2024, China's production capacity of polyvinyl alcohol is 1.096 million tons per year, making it the country with the most complete raw material routes and the largest production capacity of polyvinyl alcohol in the world.   The production capacity of polyvinyl alcohol in China is mainly concentrated in the East China (Anhui Province, Shanghai City, and Jiangsu Province), North China (Inner Mongolia), and Northwest China (Ningxia) regions. In 2024, the total production capacity of these three regions is 786000 tons per year, accounting for approximately 71.72% of the total production capacity.   The production of polyvinyl alcohol in China adopts the ethylene method and acetylene method processes. In 2024, the total production capacity using the calcium carbide acetylene method is 660000 tons per year, accounting for approximately 60.22% of the total production capacity; The total production capacity using the ethylene method is 276000 tons per year, accounting for approximately 25.18% of the total production capacity; The total production capacity using natural gas acetylene method is 160000 tons per year, accounting for approximately 14.60% of the total production capacity. Among the 10 polyvinyl alcohol production enterprises in China, except for Changchun (Jiangsu) Chemical Co., Ltd., all other production enterprises have supporting facilities for producing vinyl acetate raw materials. Anhui Wanwei Group Co., Ltd. is the largest polyvinyl alcohol production enterprise in China, with a production capacity of 310000 tons per year (including Guangwei and Mengwei production capacity) in 2024, accounting for about 28.28% of the total domestic production capacity. It is distributed in Chaohu, Anhui (headquarters), Hechi City, Yizhou District, Guangxi, and Chahar Right Rear Banner, Inner Mongolia. It can produce products with different degrees of polymerization and alcoholysis, mainly including PVA 1799, PVA 2699, PVA 0499, PVA 0599, PVA 1788, and PVA 0588.   Import and export analysis   According to relevant statistical data from the General Administration of Customs of China, from 2019 to 2024, the import volume of polyvinyl alcohol in China showed a development trend of first increasing year by year, then decreasing year by year, and then increasing again. In 2024, China's imports of polyvinyl alcohol will mainly come from Japan, Singapore, Taiwan, China, the United Kingdom and the United States. The total import volume will reach 33400 tons, accounting for 90.03% of the total import volume, with a year-on-year growth of 23.70%. Among them, Japan is the largest source of imports, with an import volume of 18700 tons, accounting for 50.40% of the total import volume, a year-on-year increase of about 28.08%; Next is Singapore, with an import volume of 6500 tons, accounting for approximately 17.52% of the total import volume, a year-on-year increase of approximately 27.45%; In addition, the import volume from Taiwan, China was 3700 tons, accounting for 9.97% of the total import volume, with a year-on-year growth of about 8.82%; The import volume from the United States is 0.25 million tons, accounting for approximately 6.74% of the total import volume, a year-on-year increase of approximately 8.70%; The import volume from the UK was 0.2 million tons, accounting for approximately 5.39% of the total import volume, a year-on-year increase of approximately 33.33%.    In 2024, the import of polyvinyl alcohol in China will mainly be concentrated in four provinces and cities: Zhejiang, Shanghai, Tianjin, and Yunnan, with a total import volume of 31000 tons, accounting for about 83.56% of the total import volume, a year-on-year increase of about 35.37%. In 2024, the import of polyvinyl alcohol in China will mainly be through two trade modes: general trade and processing trade, with a total import volume of 36700 tons, accounting for about 98.92% of the total import volume and a year-on-year growth of about 19.54%.   From 2019 to 2024, the overall export volume of polyvinyl alcohol in China showed a development trend of first decreasing and then increasing year by year (except for 2023). The export volume in 2024 reached its highest value in recent years, reaching 210200 tons, a year-on-year increase of about 14.30%. The corresponding export unit price shows a development trend of first decreasing, then increasing year by year, and then decreasing year by year. The export unit price in 2019 was $1750.36 per ton, and in 2020 it was the lowest value in recent years at $1610.37 per ton, a year-on-year decrease of about 8.00%. The export unit price in 2022 reached its maximum value of 3576.60 US dollars per ton, a year-on-year increase of about 52.01%. The export unit price for 2024 is $1744.19 per ton, a year-on-year decrease of approximately 11.99%.   In 2024, China's polyvinyl alcohol was mainly exported to India, Pakistan, Italy, Russia, South Korea, Turkey, Malaysia and Indonesia, with a total export volume of 115100 tons, accounting for 54.76% of the total export volume, with a year-on-year increase of about 5.50%.   In 2024, the export of polyvinyl alcohol in China will mainly be concentrated in five provinces, municipalities, and cities including Shanghai, Jiangsu, Anhui, Inner Mongolia, and Hubei, with a total export volume of 181900 tons, accounting for approximately 86.54% of the total export volume and a year-on-year increase of approximately 17.43%.   In 2024, China's polyvinyl alcohol exports will mainly consist of two trade modes: general trade and logistics goods under special customs supervision. The total export volume will reach 209500 tons, accounting for 99.67% of the total export volume and a year-on-year increase of about 14.42%. The export volume of general trade mode is 208300 tons, accounting for 99.10% of the total export volume, with a year-on-year increase of about 14.26%; The export volume of logistics goods trade in the customs special supervision area is 1200 tons, accounting for about 0.57% of the total export volume, a year-on-year increase of about 50.00%.   Consumption Status and Development Prospects   From 2019 to 2024, the apparent consumption of polyvinyl alcohol in China showed an overall trend of first increasing, then decreasing, and then with relatively small changes in growth rate. The apparent consumption in 2019 was 652400 tons, reaching the highest value in recent years of 684600 tons in 2020, a year-on-year increase of about 4.94%. The consumption in 2023 is the lowest in recent years at 547200 tons, a year-on-year decrease of about 8.43%. The apparent consumption in 2024 is 576900 tons, a year-on-year increase of about 5.43%. The self-sufficiency rate of the corresponding product was 120.17% in 2019, a year-on-year increase of about 2.92%; In 2024, it will be 130.01%, a year-on-year increase of about 1.63%.   In recent years, while the total consumption of polyvinyl alcohol in China has remained stable, the consumption structure has been continuously optimized, and the proportion of downstream high value-added demand has increased. The consumption structure of polyvinyl alcohol in China in 2024 is as follows: the demand for polymerization additives accounts for about 12.0% of the total consumption, fabric pulp accounts for about 18.0%, PVB resin accounts for about 7.0%, vinylon fiber accounts for about 10.0%, papermaking pulp and coatings account for about 8.0%, adhesives account for about 40.0%, and other aspects account for about 5.0%.   With the steady growth of China's economic construction, the demand for high support and high-density high-end textiles, high-end papermaking chemicals, automotive and building safety glass, PVB resin and film, biodegradable polyvinyl alcohol film, etc. will steadily increase. Due to the excellent performance of polyvinyl alcohol fibers, they can replace harmful asbestos materials in the construction cement industry, and the demand for polyvinyl alcohol will continue to grow in the future. In addition, the further development of infrastructure construction will bring new opportunities for the development of polyvinyl alcohol in the adhesive market. In addition to the demand in other fields such as fine chemicals and pharmaceutical chemicals, it is expected that the demand for polyvinyl alcohol in China will continue to grow steadily in the future, with a total demand of about 700000 tons by 2028. However, the structural supply-demand contradiction is prominent, and market competition will become more intense.  

  introduction In the morning, tearing open a bag of individually packaged coffee powder; in the afternoon, taking out a box of properly preserved fruit slices from the refrigerator; in the evening, unpacking the corrugated cardboard box delivered by online shopping - behind these seemingly ordinary life scenarios, there is a key material "shadow" active: polyvinyl alcohol (PVA) coating material. As the "invisible champion" of the packaging industry, PVA coating technology is quietly revolutionizing our daily lives. This article will take you on an in-depth exploration of this material technology that is changing the rules of the packaging industry. From what is PVA, why use PVA, and what to pay attention to when coating PVA, it reveals how PVA builds an innovative bridge between environmental protection and functionality.     What is PVA Polyvinyl alcohol (PVA), as a fully synthetic water-soluble polymer, possesses a unique "hydrophilic character" due to the densely packed hydroxyl groups on its molecular chain. This seemingly contradictory property—starting from hydrophobic vinyl monomers but forming a hydrophilic polymer—is precisely where the magic of PVA technology lies. In industrial applications, PVA products are finely categorized based on two dimensions: polymerization degree, including low polymerization degree (DP<1000), medium polymerization degree (1000<DP<2000), and high polymerization degree (DP>2000); and alcoholysis degree, including low alcoholysis degree (<80%), partial alcoholysis (79-89%), medium alcoholysis (91-98%), and complete alcoholysis (98-99%). This multi-level classification system enables PVA to precisely match the needs of different application scenarios. In the coating industry, commonly used PVA models include 1799, 2099, 2299, etc. The "17" and "22" represent the polymerization degree, while "99" indicates an alcoholysis degree of up to 99%. Coatings formed from such high alcoholysis PVA exhibit excellent barrier properties and mechanical strength. When PVA molecules dissolve in water, the hydroxyl groups form a hydrogen bond network with water molecules, transforming PVA into a transparent viscous colloidal solution. This characteristic makes it an ideal carrier for coating processes. In solution form, PVA molecules can spread evenly on the substrate surface, forming a continuous and dense film after drying, thereby exerting its core functions.   Reasons for using PVA in the industry 03 in today's increasingly stringent environmental regulations, PVA stands out by virtue of its unique degradability. . However, the environmental performance is only the beginning of the story. The core value of PVA coating is more reflected in its multi-functional integration characteristics:   PVA molecules are full of groups (hydroxyl groups) that like to "hold hands" with each other, and they will form an extremely dense "net" by holding hands in a dry state. . Especially when the molecules are arranged neatly (crystallized), the effect is better.   (2) PVA (polyvinyl alcohol) material with adjustable mechanical properties can adjust its hardness, elasticity and strength as "plasticine". The key is that its molecular structure is like a long chain full of "small hooks" (hydroxyl, -oh). These "little hooks" especially like to hold hands with each other (forming hydrogen bonds), and we can control the tightness and mode of their "holding hands" through some methods, so as to change the properties of the material. For example, by adding nanoparticles, the density of hydrogen bond network increases and the rigidity of materials is improved; Plasticizers can also be added to reduce intermolecular hydrogen bonds, thereby improving ductility and transparency.   (3) The composite compatible PVA coating exhibits excellent adhesion to various substrates. Research has shown that modified PVA coating solution can directly form stable coatings on the surfaces of plastic films such as PET, BOPP, PE, etc., without the need for complex surface treatment processes. This' friendly personality 'makes PVA an ideal intermediate layer for composite materials.   (4) Function Expansion Platform The hydroxyl groups in PVA molecules act as "chemical handles" and can be modified through esterification, cross-linking, blending, and other methods to introduce new functions. Adding nano titanium dioxide can enhance water resistance; Composite organic acids can enhance moisture resistance; Integrating antibacterial agents can achieve antibacterial function - the multifunctionality of PVA provides a broad platform for packaging innovation.   Key parameters of PVA coating process   (1) Formula system: The precise and balanced artistic typical high barrier PVA coating liquid formula contains a precise ratio of 10-15% PVA solids and 85-90% water, and adds various functional additives based on PVA quality: 25-28% plasticizers (glycerol, polyethylene glycol), 3-5% emulsifiers (such as amide propyl betaine), 5-7% anti adhesive agent (caprolactam), and 1-3% release agent (Tween-80).   (2) Dispersion grinding: The preparation of breakthrough solutions at the nanoscale requires a rigorous dispersion procedure: a high shear disperser is used to process at a speed of 1500-2000 revolutions per minute for 0.5-1 hour, followed by grinding in a sand mill to a particle size of less than 100 nanometers. This process returns inorganic additives (such as titanium dioxide) to their original particle size, significantly improving the density and self leveling performance of the coating.   (3) Coating equipment: The precision transfer art coating process adopts a specially designed mesh roller with an "eight" shaped opening design, with a mesh to wall ratio controlled between 10:1 and 15:1, and a mesh size of 100-500. These parameters together ensure that the coating is evenly transferred to the substrate surface with a precision coating amount of 3-10g/m ². The speed of the coating machine needs to be stably controlled within the range of 20-300/min to achieve a perfect balance between efficiency and quality.   (4) Drying and solidification: shaping of microstructure   The coated material needs to be accurately dried in a hot air environment of 105-115 ℃. This stage not only removes moisture, but also promotes the orientation crystallization and cross-linking reaction of PVA molecular chains, forming a stable three-dimensional network structure. The temperature control accuracy of ± 2 ℃ is crucial, as too low a temperature can cause residual moisture to affect the barrier properties; If it is too high, it will cause thermal degradation   Common problems and solutions   (1) Analysis of reasons for uneven coating (horizontal stripes): changes in viscosity of the slurry (caused by solvent evaporation), clogging of the mesh roller, and deviation in parallelism of the back roller Solution: ▶  Install online viscometer for real-time monitoring and replenish volatile solvents ▶  Adopting the "outer eight character" baffle design to eliminate bulging edges ▶  Regularly calibrate the parallelism of the back roller (error ≤ 0.01mm/m)   (2) Analysis of surface defects (scratches/particles): Agglomerated particles in the slurry (not fully dispersed), small gaps in the scraper, and environmental dust pollution Solution: ▶  Implement two-stage filtration (100 μ m+50 μ m filter combination) ▶  Using sapphire material scraper, regularly inspect the blade edge under a microscope ▶  Improve the cleanliness standards of the coating workshop   (3) Cause analysis of powder loss problem (coating powdering): caused by over drying (thermal degradation), low environmental humidity, and insufficient water absorption of the substrate Solution: ▶  Adopting segmented drying: 90 ℃ (pre drying) → 110 ℃ (main drying) → 80 ℃ (rewetting) ▶  Workshop humidity control within the range of 50 ± 5% RH ▶  Substrate pretreatment (corona treatment to enhance wettability)   (4) Analysis of reasons for insufficient adhesion: insufficient surface tension of the substrate, high crystallinity of PVA, and fast drying rate Solution: ▶  Base material corona treatment (dyn value ≥ 40mN/m) ▶  Add 0.5-1% polyethylene glycol 400 to reduce crystallinity ▶  Using infrared preheating substrate (60 ℃) to enhance interface bonding   (5) Analysis of Reasons for Insufficient Water Resistance: Exposure of PVA Hydrophilic Groups, Insufficient Crosslinking Degree, and High Environmental Humidity Solution: ▶  Add 3-5% rutile type nano titanium dioxide (particle size ≤ 50nm) ▶  Adopting succinic acid/citric acid synergistic crosslinking (swelling degree reduced by 86%) ▶  Surface coating with 0.5 μ m hydrophobic protective layer (PVB based)   Finally   When PVA molecular chains are oriented and arranged on the substrate, it forms not only a nanoscale barrier layer, but also a revolution in material genes: 1.The natural contradiction between water solubility and high barrier, 2. Achieving a perfect reconciliation of environmental mission and commercial value, finding the golden intersection point through coating technology. In the future, with the implementation of corresponding new standards and the mass production of bio based PVA, this green storm caused by "polyvinyl alcohol" will sweep from packaging bags to photovoltaic cells, sustained-release drug capsules, flexible electronics... Enterprises that master the core technology of PVA coating will rewrite the underlying code of material civilization.

  Product information: English name: Poly vinyl alcohol CAS number: 9002-89-5 Molecular formula: (CH2CHOH)n Storage conditions: Store in a cool, sealed place   Characteristics: White to slightly yellow powder or translucent granules, odorless, tasteless, non-toxic, and non-corrosive. It is easily soluble in water and also soluble in solvents containing hydroxyl groups, such as glycerol, ethylene glycol, acetic acid, acetaldehyde, benzoic acid, etc. It is insoluble in general non-polar organic solvents and inorganic acids.   Product Introduction： Polyvinyl alcohol (PVA) is produced through polymerization and alcoholysis of vinyl acetate. Its molecular formula is (CH2CHOH)m(CH2CHOCOCH3)n, and it is a stable, non-toxic, water-soluble polymer. The polyvinyl alcohol series encompasses various product types. Different types of polyvinyl alcohol are typically identified by four-digit numbers, where the first two digits multiplied by 100 represent the degree of polymerization, and the last two digits indicate the degree of alcoholysis. The properties of polyvinyl alcohol (PVA) are primarily determined by its degree of polymerization and degree of alcoholysis. Fully alcoholyzed PVA is characterized by the presence of few residual hydrophobic acetate groups in its molecules, orderly molecular arrangement, a large number of hydroxyl groups, and strong hydrogen bonding. It is a crystalline polymer with high strength. Non-fully alcoholyzed PVA can be regarded as a macromolecule formed by the copolymerization of vinyl alcohol and vinyl acetate. Vinyl alcohol has strong hydrophilicity, while vinyl acetate is lipophilic. This amphiphilic structure determines that PVA macromolecules with low alcoholysis degree possess both properties of increasing water viscosity and reducing oil-water interfacial surface tension. The viscosity of fully alcoholized PVA increases with time and gradually gelates, which can be restored after reheating. Adding sodium sulfate, potassium sulfate, ammonium sulfate, and borax can all produce a gel. Some alcoholized PVA solutions do not produce a gel. In addition, the numerous weak non-covalent bonding forces, such as hydrogen bonds and van der Waals forces, present within the PVA system significantly affect its water solubility. The residual acetate groups of partially alcoholized PVA macromolecules can weaken hydrogen bonds between adjacent macromolecules and within the macromolecules, thereby improving the water solubility of PVA. However, the increase in acetate groups leads to a decrease in the critical temperature for phase separation, resulting in a gradual decrease in water solubility at high temperatures. For example, PVA with an alcoholysis degree of less than 60% is insoluble in water above 40℃. PVA1799 is a polyvinyl alcohol polymer with a polymerization degree of 1700 and an alcoholysis degree of 99%. It is soluble in hot water above 95°C, and the aqueous solution has good adhesive properties and film-forming properties. An aqueous solution with a concentration greater than 10% will gel and freeze at room temperature, and will become thinner and regain fluidity at high temperatures.   Application: Under external influence, PVA can undergo physical and chemical crosslinking. PVA prepared by the cyclic freeze-thaw method can exhibit rubber-like elasticity, and its mechanical properties are unmatched by most current hydrogels. PVA's strong tensile and compressive properties, as well as its good flexibility and ductility, make it an ideal candidate for flexible substrates, laying a good foundation for the development of wearable and implantable medical devices. In addition, PVA can also be used as a hydrogel substrate to construct hydrogel materials by combining with different types of polymers and nanoparticles, thereby obtaining superior mechanical and biological properties that match many biological tissues to meet application needs.    

Introduction: In the first half of 2025, the PVC paste resin industry struggled to advance amidst a complex landscape intertwined with multiple external variables. The ex-factory price of PVC paste resin once fell to a five-year low, dropping below 6,000 yuan/ton. The increase in supply from upstream enterprises and the continuous decline in raw material prices led to insufficient cost support, resulting in a weak trend of profit pressure in the industry as a whole. Analysis of paste PVC resin supply trend from January to June 2025 In the first half of 2025, the total supply of PVC paste resin increased. Currently, the total production capacity nationwide stands at 1.515 million tons, an increase of 20,000 tons compared to the end of 2024. Figure 2 shows the proportion of PVC paste resin production capacity in each region in the first half of 2025 Based on the regional division of production capacity of manufacturing enterprises, the domestic production capacity of PVC paste resin is primarily distributed in the northwest region, accounting for a whopping 42% of the total; followed by the north and east China regions, each accounting for 20%; the northeast region ranks fourth with a share of 14%. Shenyang Chemical Industry Co., Ltd. expanded its production capacity by 20,000 tons in the first quarter and is currently the largest PVC paste resin manufacturing enterprise in the country, with a total production capacity of 220,000 tons; the central region has the smallest share, accounting for 4%. From the perspective of maintenance, PVC paste resin production enterprises experienced less maintenance in the first half of 2025. However, as supply gradually saturated in the second quarter, inventory pressure on traders and enterprises continued to rise, and some enterprises temporarily reduced their production capacity. Shandong Langhui and Jinxiang Materials began to shut down for maintenance according to their previous maintenance plans, resulting in a significant decrease in inventory and total market supply, and a slight increase in prices. Nevertheless, the overall operating rate in the first half was 4% higher than that of the same period last year, with many enterprises focusing their maintenance on the third quarter. Review of PVC paste resin market prices from January to June 2025 From January to June 2025, the market price of PVC paste resin exhibited a general downward trend with fluctuations. In the first half of 2025, the market price of PVC paste resin in China steadily declined. High supply pressure and sluggish demand led to an imbalance between supply and demand in the market, causing the price center of gravity to continuously decline and market confidence to suffer significant damage. Before the Spring Festival in January and February, market prices remained relatively high, with downstream stocking and inquiry activities being relatively active, but the intensity of receiving orders was limited, with purchases mainly driven by rigid demand. After the Spring Festival, the market's ability to receive goods was generally moderate. Coupled with the expansion of production capacity by 20,000 tons at Shenyang Chemical and the relatively low number of industry maintenance devices, the domestic PVC paste resin market faced high supply pressure. Prices gradually declined from the Spring Festival until mid-April, and around April 20th, prices fell to their lowest level in recent years. Some PVC paste resin manufacturers began sporadic load reduction, with Shandong Langhui and Jinxiang Materials shutting down for maintenance, alleviating market supply pressure and causing prices to rebound from their lows. Coupled with the renegotiation of tariffs between China and the United States in May, PVC paste resin entered a phase of slight increase, but the upward trend was limited. Prices declined again from the end of May. During the previous low-price period, end-user factories and traders had stocked up significantly, and coupled with the arrival of the high-temperature off-season in East and South China in June, demand was generally moderate, and low export prices led to increased pressure on domestic trade, causing prices to hit the bottom again. The price fell to the previous low point, showing a weak but stable trend.   From the perspective of supply side, the maintenance arrangements for enterprises in the third quarter are relatively concentrated. The earliest enterprise with a maintenance plan is China Salt Inner Mongolia Chemical, which will commence maintenance at the end of July. Prior to this, no other enterprises are scheduled for maintenance, so it is expected that the supply volume will remain high during July. Additionally, Inner Mongolia Junzheng and Ningbo Formosa Plastics plan to conduct maintenance at the end of August. Overall, the capacity utilization rate of PVC paste resin manufacturers may only decline in July and August. The demand side is also not optimistic. The operation of the PVC glove market is relatively stable, with the overall industry production line maintained at around 400 units. Downstream factories of bulk materials are facing severe challenges during the high-temperature off-season, and the number of enterprises choosing to reduce production or shut down for holidays is gradually increasing. Against this backdrop, it is expected that the purchasing enthusiasm in the demand market will significantly weaken. In terms of the import and export market, the situation is also quite severe. The price of glove materials in foreign markets is low, with a significant price advantage, which puts pressure on domestic sales of paste resin. At the same time, due to the lack of price competitiveness, the phenomenon of exporting paste resin for domestic sales has increased, further exacerbating the supply situation in the domestic market. Considering various factors such as supply, demand, and import and export, bearish news is frequent in the current market. Under these circumstances, the domestic PVC paste resin market is expected to show a weak and steady decline in the short term, with manufacturers flexibly adjusting prices based on sales conditions.
