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.

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%.

Injection grade white masterbatch according to the type of plastic used in the product, the sameplastic raw material is selected as the carrier, the special color masterbatch has better compatibilityand dispersion, and meets the environmental protection requirements. High gloss, colorless spot, good yellowing resistance, impact strength retention rate 288% tensile strength retention rate >90%. Customers can adiust the amount themselves according to their requim-ent.3%~6%amount is recommended,special production add 10%.
