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.
Titanium dioxide in the rubber industry acts as both a colorant and a reinforcing, anti-aging, and filling agent. Adding titanium dioxide to white and colored rubber products enhances sun resistance, preventing cracking and discoloration under sunlight, while also improving elongation and resistance to acids and alkalis. Titanium dioxide for rubber is mainly used in automobile tires, rubber shoes, rubber flooring, gloves, and sporting goods, primarily in the rutile form. However, in automobile tire production, a certain amount of anatase type is often added to enhance ozone and UV resistance.
The application of titanium dioxide in cosmetics is also becoming increasingly widespread. Because titanium dioxide is non-toxic and far superior to lead white, almost all kinds of face powder use titanium dioxide to replace lead white and zinc white. Only 5%-8% titanium dioxide needs to be added to face powder to achieve a permanent white color, making the powder smoother, providing better adhesion, absorption, and coverage. In water-based paints and cold creams, titanium dioxide can reduce the greasy and transparent feeling. It can also be used in various other fragrances, sunscreens, soap flakes, white soap, and toothpaste.
Porcelain glaze made with titanium dioxide has strong transparency, light weight, high impact resistance, good mechanical properties, vibrant colors, and is not easily contaminated. Food and pharmaceutical grade titanium dioxide is characterized by high purity, low heavy metal content, and strong covering power.
