Precipitated calcium carbonate selects high ourity limestone and mineral water as raw material, is made through process of calcining, chemical reacition, reselection, dehydration, drying and depolymerization. It is pure and stable filler whose bulk densit y is small.
Application: Heavy (Ground) Calcium Carbonate is widely used as filler and improver in plastic, paint, paper-making, rubber, pharmacy, feed, daily chemical, ceramics, adhesives and ink industry.
