Product Aplication
1.Rubber industry
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 industrial
In plastic products, keeping stablity of the products, strengthen the products, keeing surface smoothly
3.Painting
PCC is innocuous, white color, and has good stability, as the filler in paints, avoid the paint settlement, easy get dispersed, make good glossiness
4.Papermaking
Whitening the paper, and as the fller, can reducing the pulp for saving the cost.
