R-311 is a rutile TiO2 with multiple uses produced via sulfate process. lt is inorganically coated by zirconium and aluminum and organically treated. With good hydrophilia, lipophilicity,dispersity,temperature resistance and blue bottom phase,high brightness and gloss, it is widely used to coating,ink,plastics etc.

R-321 is a rutile Ti02 via sulphate process. With special inorganic and organic surface treatment,it has an excellent stable blue phase, high and easy dispersibility, high opacity, low volatilecontent, and anti-yellowing of high temperature, etc. lt can be well applied in the plastic systemin high concentration Ti02,such as color masterbatch,casting film,interrior plastics.etc.

R-211 is a rutile TiO2 untreated grade via sulfate process,customarily called crude TiO2. It is widely used to papermaking, decorative paper, plastics, paint, ink, rubber, color masterbatch, etc. As it is untreated,so it is also a necessary raw material for rutile post-coating treatment.
