Specifications

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 multi-selection and secondary depolymerization. It is pure and stable filler whose bulk density is small.
Main application:
It is widely used as filler in making rubber, plastic, paper, paint, printing ink etc, it can not only be used in waking chemical products such tooth powder, toothpaste and cosmetics, but also in organic synthesis, metallurgy and making glass and as best.
