2023-03-11
Titanium dioxide is divided into two types: rutile type and anatase type. According to international practice, the rutile type is represented by the first letter R of its English Rutile, which is called R type; the anatase type is represented by the first letter A of its English Anatase, and is called A type.
The rutile type and anatase type without post-treatment are called R1 and A1 types, respectively; the post-treated rutile type and anatase type are called R2, R3, and A2 types, respectively. The anatase titanium dioxide used for plastics is called AP type; the anatase titanium dioxide used for chemical fibers is called AH type.
Application of titanium dioxide
Titanium dioxide is not only used as a colorant in the rubber industry, but also has the functions of reinforcement, anti-aging and filling. Adding titanium dioxide to white and colored rubber products, under sunlight, it is resistant to sunlight, does not crack, does not change color, has high elongation and acid and alkali resistance.
Titanium dioxide for rubber is mainly used in automobile tires, rubber shoes, rubber flooring, gloves, sports equipment, etc., and generally anatase is the main type. However, for the production of automobile tires, a certain amount of rutile products are often added to enhance the anti-ozone and anti-ultraviolet capabilities.
Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic and far superior to lead white, almost all kinds of fragrance powder use titanium dioxide to replace lead white and zinc white.
