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.
