Product Uses: Titanium Dioxide (CAS#13463-67-7)
Our titanium dioxide (TiO₂) is a multi-purpose white pigment and performance additive engineered to improve the characteristics of end products for a broad spectrum of industries.
Within paints and coatings, it delivers superior hiding power, brightness and weatherability, enabling long-lasting colour retention. When incorporated into plastics, it boosts UV stability, mechanical strength and whiteness, rendering it perfect for outdoor exposure applications.
For cosmetic formulations, it acts as a physical UV filter that delivers broad-spectrum ultraviolet protection, whilst creating a silky, refined texture in skincare and cosmetic products.
Classified as food additive E171, it safely delivers colour enhancement for beverages, confectionery, dairy goods and more. In pharmaceutical manufacturing, it works as a non-toxic opacifier and film-coating agent for tablets and capsules.
Moreover, it elevates brightness and opacity in paper, textiles and rubber. Thanks to outstanding chemical inertness, it is also applicable to ceramics, printing inks and adhesives.
We supply customisable rutile and anatase grades that comply with global standards including FDA and REACH, guaranteeing flexibility and safety even for rigorous application requirements.
