Rutile titanium dioxide applications
In the rubber industry, titanium dioxide serves as both a colorant and a reinforcing, anti-aging, and filling agent. Adding titanium dioxide to white and colored rubber products enhances their sunlight resistance, preventing cracking and discoloration, while improving elongation and acid/alkali resistance. Titanium dioxide for rubber is mainly used in car tires, shoes, rubber flooring, gloves, and sports equipment, generally in the rutile form. However, in car tire production, a certain amount of anatase type is often added to enhance ozone and UV resistance.
