Titanium dioxide is an important inorganic chemical pigment. It can not only significantly improve the whiteness and gloss of plastics and rubber, but also has good color stability and can enhance the visual effects and texture of products. In addition, titanium dioxide can also absorb and scatter ultraviolet rays, reducing the damage of ultraviolet rays to plastic products and rubber molecules, thus improving their light resistance and weather resistance, effectively avoiding aging, yellowing and other phenomena.
