I. Product Introduction: Light (precipitated) calcium carbonate
This product is made of high-purity limestone and is produced through the processes of calcination, digestion, multi-stage selection, neutralization, dehydration, drying and depolymerization. It adopts a unique multi-stage refining and secondary depolymerization process. The product is pure, stable and has high whiteness. It is a universal filling raw material with a low bulk density.
