Heavy calcium carbonate

Heavy calcium carbonate,simply called heavy calcium, is a white powder made of fine calcitelts chief composition is CaCO3. Calcium stearate displays such properties as whiteness, purity, soft colour and stability in chemical composition. Therefore calcium stearate is a very good filling widely used in industry.

Application:

1. In rubber manufacture: Calcium carbonate was the earliest filler used in the rubber industry. It can enlarge the capacity in the rubber products, for saving the cost. It also enhance the tensile strength, abrasion and tearing strength.

2. Plastic manufacture: As the framwork in plastic products, keeping stablity of the  products, strengthen the products, keeing surface smoothly. Since the calcium carbonate is hight white, it can place the expensive the white ployethylene, for whitening the plastic products.

3. Paper making: Whitening the paper, and as the fller, can reducing the pulp, for saving the cost etc.
