calcium carbonate 471-34-1
Category : Inorganic chemicals
CAS NO : 471-34-1 EC NO : 207-439-9 MF : CaCO3 MW : 100.088 Product description : Product Description Nano precipitated calcium carbonate for PVC CC-R series product is a type of functionally filler, is a tasteless white powder upon surface treatment by organic substance. The particle diameter is 20-90nm, and crystal shape is 'cubic'. It has following advantages: High whiteness, good dispersing ability, high surface activeness and regular particles. 1) Applicable characteristics: Used in plastic, it has good affinity with resin, so as to increase or adjust the rigidity, tenacity, and bending intensity effectively. It may also improve the rheology of plastic processing system, decrease the plasticization temperature so as to improve the stability, heat-resistance and surface brightness of products. Used in NR, BR, SBR and other rubber systems, it is easily mixed refined, regularly dispersed. It will also make the adhesive 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, high tension-resistance strength, mild temporary reformation as well as good anti-bending capability and high anti-avulsion strength. 2)Applicable scope: Filler and feature-change of PVC, PE, PP, ABS resin; Particles of sheath of high standard wires and cables; PVC leatheroid, PVC profile, Particle of TPR, PVC threads, all type of pipe material and section material, rubber products, etc Uses : Used in plastic, it has good affinity with resin, so as to increase or adjust the rigidity, tenacity, and bending intensity effectively.
