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.

High quality calcium powder and additives are used, which are cut by air cooling throughhigh-speed refining and extrusion. The surface crystal points of the film products are less after useand conform to GBT20197-2006.Standard. High whiteness, high brightness, uniform dispersion, firm sealing. Direct blow type, add 100%.

R-221 is a rutile TiO2 via sulfate process.After special surface treatment, it has an excellent dry powder flow, hydrophobic, low moisture absorption, high temperature anti-yellowing. Can be easily dispersed in the plastic system, and applied to high temperature casting film and other high temperature processing technology.It is wildly used to color masterbatch,plastics,rubber,etc.
