1. Product Introduction:
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 technicals of particular multi-selection and secondary depolymerization. It is pure and stable filler whose bulk density is small.
