Titanium dioxide for rubber, mainly used in automobile tires and rubber shoes, rubber floor, gloves, sports equipment, etc., is mainly anatase. However, a certain amount of rutile products are often added in the production of automobile tires to enhance the ability of anti ozone and anti ultraviolet.
