Rutile titanium dioxide R-902
Product Introduction
Rutile - type titanium dioxide R - 902 is a rutile - type titanium dioxide produced by the sulfuric - acid process. It undergoes inorganic surface treatment with zirconium oxide and aluminum oxide, and surface modification with special organic treatment agents. It features a high blue - phase, easy dispersibility, high weather resistance, high hiding power, low oil absorption, good system compatibility, and excellent processing rheology. It is an oil - biased, high - quality titanium dioxide dedicated to plastics, as well as a general - purpose product.

Application Characteristics
Blue undertone：The average particle size of R - 902 is close to the theoretical particle size of titanium dioxide. TiO₂ with a smaller particle size can scatter blue light more effectively than that with a larger particle size. Therefore, it has a bluer base phase and excellent whiteness.
Excellent dispersibility：The special inorganic and organic surface treatments reduce the contact between TiO₂ particles, enabling R - 902 to exhibit excellent dispersibility during application. As a result, it has good wettability and is easy to grind.
Low Oil Absorption：The low oil absorption of R - 902 enables titanium dioxide to maintain good processing performance during its application in plastics.
High Weather Resistance：R-248 adopts the zirconium coating treatment process, which improves the weather resistance and heat resistance of titanium dioxide, resulting in very stable chemical properties.
Good System Compatibility：The special organic surface treatment of R - 902 makes it very suitable for non - polar and oily systems, thus exhibiting good system compatibility in applications.
Packaging:It is packed in 25-kilogram paper-plastic composite bags or 500-kilogram and 1,000-kilogram plastic woven bags.
Product Storage：As long as it is protected from moisture, it can be stored for a long time.
Protection:When handling TiO2, gloves and a protective shield should be worn. In case of skin contact, this compound poses no danger, but it is recommended to wash the skin after use.
