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. Titanium dioxide is added to white and color rubber products. Under sunlight, it is resistant to sunlight, no cracking and discoloration, large elongation and acid-base resistance. Titanium dioxide for rubber is mainly used for automobile tires, rubber shoes, rubber floors, gloves, sports equipment, etc. it is generally anatase. However, for the production of automobile tires, a certain amount of rutile products are often added to enhance the ability of anti ozone and anti ultraviolet.
