caco3, coated light calicum carbonate

Developed by our company and made from high-quality Calcium Carbonate. By selected activating agent and coupling agent, together with surface treat, we designed various types for different application.
JSH-1 (General use)
Widely used in various plastic product. It can replace portion of resin to reduce cost. For PVC, it can be blended into PVC resin with ratio of 10-24. For PP/PE, by mixing and activating, mixing ratio can be up to 10-25%. There is no need to change equipment and technology.

JSH-2 (Plastic use)
Widely used in plastic products with effect of quality-improving and cost-reduction. Adding CaCo3 will greatly increase production output and improve the processing capacity. For rigid PVC products,it can accelerate gelation, enhance cold impact strength, eliminate plate out, improve surface gloss. For PP/HDPE, it can enhance impact strength, yield value and tenacity.
