Calcium Carbonate Light

STAR BRAND

Our light calcium carbonate is a high-whiteness, less-impurity and high-quality calcium carbonate that is synthesized by using good-quality limestone as a raw material.
The product is used as white filler in various types of rubbers, plastics, paints, papers, etc.

EC

Our EC grade product is in the form of a relatively high-purity fine powder that is developed as a raw material for electronic products and fine ceramics.

ME-L

Our ME-L grade product improves workability and handling via a stable bulk density.
It can be used in general chemical applications, dentifrices, food additives, and fine chemicals.
