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.

R-321 is a rutile Ti0z 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.
