CR-350 Titanium Dioxide

CR‑350 is a rutile titanium dioxide manufactured via the chloride process. It adopts high‑quality titanium tetrachloride (TiCl₄) as raw material, with sophisticated oxidation technology, composite inorganic coating and organic surface treatment. It is characterized by excellent particle size distribution, high brightness and superior weather resistance.
Benefiting from its outstanding comprehensive properties, CR‑350 is recommended for high‑gloss and high weather‑resistance coatings, printing inks, outdoor polymer materials and other applications.
25 kg per paper‑plastic composite bag. Custom packaging options are available upon customer request.
