The main use of calcium carbonate is in the construction industry, either as a building material or limestone aggregate for road building or as an ingredient of cement or as the starting material for the preparation of builder's lime by burning in a kiln. Calcium carbonate is one of the most versatile substances, which is used in agriculture, industries & architecture.
Application:
Fillers of plastic such as for plastic, rubber, paper, polyvinyl chloride (PVC),Polyethylene (PE), polypropylene (PP), ABS, etc. It 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.
