Active Ground Calcium Carbonate

 

Chemical name: Active Natural Calcium carbonate

Molecular formula: CaCO₃

Properties: White delicate powder, the surface of which is covered by active material, with high dispersity to organic polymer, Have a better lipophilicity,can be fully miscibility in organic material.

Uses: Superfine Active Ground Calcium Carbonate is the important filling material of plastic, rubber and coating industry. It can reduce the cost, improve the processing ability and quality character. Can be used in thermoplastic plastics such as polyvinyl chloride (PVC) and polyene; as to synthetic resin kind of adhesives such as vinyl acetate, it can be used to improve liquidity, contractility and curing rate.

Packing: Composite plastic woven bag, 25KG/bag
