3.Mainly Applications:

a.  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 enhances the tensile strength, abrasion and tearing strength.

b.  Plastic manufacture: As the framework in plastic products, keeping stability of the products, strengthen the products, keening surface smoothly, since the calcium carbonate is high white, it can place the expensive the white polyethylene, for whitening the plastic products.

c.  Paper making: Whitening the paper, and as the filler, can reducing the pulp, for saving the cost.

 

4.Features: High whiteness, fine grain size, low impurity, adopting dry surface treatment technique, with high activation rate.
