Rubber Industry: Calcium carbonate is one of the largest industries in the use of large rubber filler. Among a large number of calcium carbonate filler in rubber, increase the volume of its products, and save expensive natural rubber, thus greatly reducing costs. Fill rubber carbonate can be higher than that of pure rubber vulcanizate tensile strength, tear strength and abrasion resistance. Plastics Industry: calcium carbonate in plastics can play a role in skeleton, the size of the stability of plastic products have a significant role, but also improve the hardness of products and increase surface gloss and surface smoothness products. Since calcium whiteness above 90%, even replace expensive white pigments. Paint industry: the amount of calcium carbonate in the paint industry is large, as in the paint in an amount of condensed 30%. Waterborne coatings industry: calcium carbonate in aqueous coatings industry uses more extensive settlement can not paint, easy to disperse, good gloss and other characteristics, in the amount of 20-60% water-based paint. Further, the important role of calcium carbonate in the paper industry, to ensure the strength and whiteness of the paper, and low cost. In the cable industry products, insulation can play a role.
