Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite.The natural Calcium Carbonate is a mineral and it is also called Ground Calcium Carbonate (GCC). VASU Minerals & Chemicals offering a quality calcite powder, and the products are survey at each and every stage at the creation operation to maintain their effectiveness and superior grade standards measure. Apart from this, their wide usage in the commercial area makes these highly demanded of calcite powder in industry.
It is widely used as an extender in paints in particular matte emulsion paint where typically 30% by weight of the paint is either chalk or marble. It is also a popular filler in plastics. Some typical examples include around 15 to 20% loading of chalk in unplasticized polyvinyl chloride (uPVC) drainpipes, 5% to 15% loading of stearate-coated chalk or marble in uPVC window profile. PVC cables can use calcium carbonate at loadings of up to 70 phr (parts per hundred parts of resin) to improve mechanical properties (tensile strength and elongation) and electrical properties (volume resistivity) (e.g. increased impact strength and High Opacity).
