Light Calcium Carbonate Application

Widely used in rubber, plastic, PVC pipes, profiles, paint, paper, paint, sealant, daily necessities, medicine, feed as filler and reinforcing agent. Not only can increase the volume, reduce the cost, more important is to improve the processing performance of the matrix, but also can play a role in strengthening, tensile, wear-resisting, tear resistance, improve luster, so calcium carbonate is not a general filler, but is known as a functional filler.
Light Calcium Carbonate with high whiteness and good fluidity is the largest filler for PVC pipes and profiles, which can increase the volume, stabilize the size, heat resistance, level off and luster of the products, thus reducing the cost and achieving the purpose of product quality.
Calcium rubber, with low oil absorption value, good reinforcement effect, wear resistance and tear resistance and other characteristics.
Special calcium coating can enhance adhesion, color firm oxidation resistance, increase fill, reduce costs and other advantages.
