Heavy Calcium

Heavy calcium carbonate, for short is heavy calcium, is made of natural carbonate minerals such as calcite, marble, limestone after grinding, which is commonly used as a powdered inorganic filler. Heavy calcium has the advantages of high chemical purity, high inertness, not easy happen chemical reaction, with good thermal stability, will not decompose below 400℃, with high whiteness, low oil absorption rate, soft, dry, with low hardness and low wear value, good dispersion, etc., so it has a wide range of applications in the preparation of rubber, plastic, paint, water-based coatings, paper making, construction, fireproof ceiling, artificial marble, floor tile and so on.
