Chemical Name: Active Natural Calcium Carbonate
Molecular Formula: CaCO3
Properties: White fine powder. The surface of the particles is covered with active substances. It is easier to disperse in organic substances than normal heavy or lightweight inactive calcium carbonate. It has better lipophilicity in organic materials. Fully miscible.
Uses: Superfine active Heavy calcium carbonate is an important filler material for the plastics, rubber and coatings industries. Can reduce costs, improve processing and improve quality performance. It can be used in thermoplastics such as polyvinyl chloride and polyolefins, and synthetic resin adhesives such as vinyl acetate to improve fluidity, shrinkage and cure speed.
