R-249 Titanium Dioxide

This product adopts special inorganic and organic coating technology. When applied in plastics, it delivers superior comprehensive performance including excellent dispersibility, high temperature resistance and anti‑yellowing property, no pinhole formation during casting at 300° C, outstanding blue‑toned whiteness and good hydrophobicity.
It is a rutile titanium dioxide specially designed for plastics, manufactured via the sulphate process. It is recommended for high‑concentration masterbatches, high‑temperature resistant plastics (such as PC, PET, ABS, etc.), cast films and other related applications.
25 kg per paper‑plastic composite bag. Custom packaging is available upon customer request.
