Calcium Carbonate

CCR is a type of functionally filler, is a tasteless white powder upon surface treatment by organic substance. The Particle diameter is 20-90nm, and shape of the crystal is 'cubic' is has following advantages; High whiteness, good dispersing ability, high surface activeness and regular particles.

1) Applicable characterstics: Used in plastic, it has good affinity with resin, so as to increase or adjust the rigidty, tenacity, and bending intensity effectively, it may also improve the rhelogy of plastic processing system, decrease the plasticization temperature so as to improve the stability, heat-resistance and soft as well as increase the processing ability of suppressing and fluidity of modules, The rubber made hereby will have a smooth surface, long extensity,

2)Applicable scope: Filler and feature-change of PVC, PE, PP, ABS resin, particles of sheath of high standard wires and cables; PVC leathered, Particle of TPR, PVC threads, all type of pipe material and section material, rubber products, etc
