Calcium Carbonate
Introduction
Calcium carbonate normally is tasteless, odorless and nontoxic, is one of the carbonate family and share the typical properties of high whiteness and chemical purity, inertness, thermostability, low oil-absorption and good dispersibility. 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 technics of particular multi-selection and secondary depolymerization. It is pure and stable filler whose bulk density is small.
Application
Calcium carbonate is widely used as filler in making rubber, plastic, paper, paint, printing ink etc, it can not only be used in waking chemical products such tooth powder, toothpaste and cosmetics, but also in organic synthesis, metallurgy and making glass and as best.
