Titanium dioxide is an inorganic compound with the chemical formula TiO2, and its appearance is white powder. It is non-toxic, best opacity, best whiteness and brilliance. As an important white pigment and porcelain glaze, the usage of titanium dioxide accounts for more than 80% of all white pigments. From a global perspective, more than 90% of the mined titanium ore is mainly used for the production of titanium dioxide pigments.
TiO2 titanium dioxide has two structures of titanium dioxide rutile (R type) and titanium dioxide anatase (A type). And the TiO2 rutile has a compact structure, is relatively stable, and has low optical activity, so it has good weather resistance. At the same time, titanium dioxide rutile has high hiding power and color reduction power, so it has better application performance. More importantly, Titanium dioxide (TiO2) is widely used in coatings, plastics, papermaking, printing, ink, chemical fiber, rubber, cosmetics and other industries.

Main Uses of Titanium Dioxide TiO2
Add titanium dioxide powder to white and colored rubber products. Under sunlight, it is resistant to sunlight, does not crack, does not change color, and has high elongation and acid and alkali resistance. Titanium dioxide TiO2 for rubber is mainly used in automobile tires, rubber shoes, rubber flooring, gloves, sports equipment, etc., and is generally dominated by anatase titanium dioxide. However, when used in the production of automobile tires, we often add a certain amount of rutile titanium dioxide to enhance its anti-ozone and anti-ultraviolet capabilities.
Because titanium dioxide is non-toxic and far superior to lead white, almost all kinds of face powders use titanium dioxide to replace lead white and zinc white. Just add 5-8% titanium dioxide to the powder to get permanent white, make the fragrance more creamy, with adhesion, absorption and covering power. Titanium dioxide in cosmetics can reduce the feeling of greasy and transparent in gouache and cold cream. Titanium dioxide is also often used in various other fragrances, sunscreens, soap flakes, white soaps, shaving creams and toothpaste.
Titanium dioxide for chemical fiber is mainly used as a matting agent. Because anatase titanium dioxide is softer than titanium dioxide rutile, titanium dioxide anatase is generally used. It does not need surface treatment, but some special varieties need surface treatment in order to reduce the photochemical effect of titanium dioxide and avoid fiber degradation under the action of titanium dioxide photocatalysis.
Titanium dioxide in food can be used as all food white pigments, the maximum usage is 1g/kg.
