Precipitated/Light Calcium Carbonate
Product Introduction:
High Whiteness Light/Precipitated 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.
