Product Usage

Titanium dioxide is a white pigment with excellent performance. In the coatings industry, it is an indispensable colorant and opacifier, providing high whiteness, hiding power, and weather resistance to coatings. In the plastics and rubber industries, it is used to enhance UV resistance and mechanical properties of products. In the paper industry, it serves as a filler to improve whiteness, opacity, and printability. Additionally, in cosmetics, due to its physical sunscreen properties, it is widely used in sunscreens and foundations to effectively reflect UV rays. It also plays a key role in the ink and ceramic industries.
