Superfine 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, more easily disperse in organic material than common ground or light unactivated calcium carbonate, with better oleophilic property, capable to fully soluble in organic material.
Use: Superfine active ground calcium carbonate is important filling material for plastic, rubber and coating industries. It can reduce cost, improve processibility and improve properties of products. It can be used in thermoplastics such as polyvinyl chloride and polyolefin. It can also be used in synthetic resin adhesive such as vinyl acetate to improve fluidity, shrinkage and solidifying speed.
Packing: Composite plastic woven bag; 25kg/bag.
