Description

Titanium dioxide (CAS 1317-80-2 ), commonly abbreviated as TiO2, is a high-performance white pigment and UV-blocking agent used across coatings, plastics, cosmetics, and construction materials. The rutile form dominates commercial supply due to its superior opacity and weathering resistance. Procurement is driven primarily by whiteness index, particle size, and surface treatment specifications. In architectural and industrial coatings, TiO2 delivers hiding power and durability, directly determining the coverage rate and exterior performance of paints and primers. Plastics and polymer compounders incorporate it to achieve opacity and UV stabilization in films, pipes, and packaging materials. Personal care formulators use it in sunscreens. In color cosmetics, it acts as a physical UV filter and white pigment. In paper and textile manufacturing, it improves brightness and opacity for paper coatings and synthetic fiber delusterants. TiO2 is supplied as a fine white powder in rutile and anatase crystal forms, with rutile grades accounting for the majority of industrial demand for chemical manufacturers. Surface-treated grades coated with alumina, silica, or organic treatments are standard for coatings and plastics applications, while uncoated grades serve specialty uses. Common specifications include technical grade, cosmetic grade, and food-contact compliant grades meeting relevant regulatory standards for global distribution and safety.
