Rutile titanium dioxide R-888 for plastic steel
Product Introduction
Rutile titanium dioxide R - 888 is a kind of rutile titanium dioxide produced by the sulfuric acid process. It undergoes inorganic surface treatment with zirconia and alumina, and surface modification with a special organic treatment agent. It has characteristics such as high blue phase, easy dispersion, high weather resistance, high covering power, low oil absorption, good system compatibility, and excellent processing rheology. It is an oil - biased, high - quality titanium dioxide specifically for plastics. It can be widely used in masterbatches, profiles, sheets, and pipes of polyolefins, PVC, ABS, PS, etc., and can also be used in the production of leather color pastes and oil - based coatings.

Application Characteristics
Blue undertone:The average particle size of R - 888 is close to the theoretical particle size of titanium dioxide. TiO₂ with a small particle size can scatter blue light more effectively than that with a large particle size. Therefore, it has a bluer undertone and excellent whiteness.
Excellent dispersibility:The special inorganic and organic surface treatments reduce the contact between TiO₂ particles, enabling R - 888 to show excellent dispersibility during the application process. As a result, it has good wettability and is easy to grind.
Low Oil Absorption:The low oil absorption of R - 888 enables titanium dioxide to maintain good processing performance during its application in plastics.
High Weather Resistance:R - 888 adopts the zirconium - coating treatment process, which improves the weather resistance and heat resistance of titanium dioxide, so its chemical properties are very stable.
Good System Compatibility:The special organic surface treatment of R - 888 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.
