Calcium Carbonate(CaCO3)
Calcium Carbonate details:
High White Light Calcium Carbonate selects high purity limestone as raw material, is made through process of calcining, chemical reaction, reselection, dehydration, drying and depolymerization. It is adopted the technics of particular multiselection and secondary depolymerization. It is pure and stable filler whose bulk density is small.
It is used for high polymer
material to improve the craftwork of processing and enhance the
mechanics and hot stability of products; It can reduce the cost
with the enhancement of dispersibility and
compatibility.

Main Applications:
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 enhances the tensile strength, abrasion and tearing strength.
2. 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.
3. Paper making: Whitening the paper, and as the filler, can reducing the pulp, for saving the cost.
