Product Overview
Titanium Dioxide (TiO₂, CAS#13463-67-7) is a high-performance inorganic compound with purity ≥99.5%, widely recognized as one of the most effective white pigments and functional additives available today.
Due to its outstanding light-scattering ability, brightness, thermal stability, and chemical inertness, Titanium Dioxide is extensively used in paints, coatings, plastics, printing materials, paper, textiles, cosmetics, food additives, and pharmaceutical formulations. In cosmetic applications, it is valued as a physical UV-blocking ingredient, while in food and pharmaceutical industries it is historically used as a whitening agent (E171 in applicable regions).
Available in high-quality rutile and anatase grades, Titanium Dioxide provides excellent customization options for different formulation needs. Its combination of superior optical performance, durability, and broad compatibility makes it an essential material for improving product appearance, functionality, and long-term performance across various industrial sectors.
