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.
