3.White powder,high quality
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.

(3)properties:
1. High purity, the majority of products containing more than 99.0% calcium carbonate;
2. High brightness, high whiteness selected flawless natural mineral products typical whiteness ≥ 95;
3. Impurity content is low
(4)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.
