Titanium dioxide is an important inorganic chemical pigment, the main component of which is titanium dioxide. The production process of titanium dioxide includes sulfuric acid method and chlorination method.  It has important applications in coating, printing ink, papermaking, plastic rubber, chemical fiber, ceramics and other industries

There are two manufacturing methods of titanium dioxide: sulfuric process and chlorinate process

The main application fields of titanium dioxide: coatings, plastics, printing ink and papermaking, of which coatings account for 60%, plastics for 20%, papermaking for 14%, and others (including cosmetics, chemical fiber, electronics, ceramics, enamel, welding rod, alloy, glass and other fields) account for 6%.

Titanium dioxide is not only used as a colorant in the rubber industry, but also has the functions of reinforcement, anti-aging and filling. Titanium dioxide is added to white and color rubber products. Under sunlight, it is resistant to sunlight, does not crack, does not change color, has a large elongation and is acid-base resistant. Titanium dioxide for rubber is mainly used in automobile tires, rubber shoes, rubber floors, gloves, sports equipment, etc. it is generally anatase type. However, for the production of automobile tires, a certain amount of rutile products are often added to enhance the ozone and ultraviolet resistance.

Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic and far superior to lead white, almost all kinds of perfume powders use titanium dioxide to replace lead white and zinc white. Permanent white can be obtained by adding 5%-8% titanium dioxide into the flavor powder, which makes the flavor more greasy, with adhesion, absorption and covering power. Titanium dioxide can reduce the feeling of greasiness and transparency in gouache and cold cream. Titanium dioxide can also be used in other spices, sunscreen, soap flakes, white soap and toothpaste.
