Calcium Carbonate



Calcium Carbonate
Product Specification

Our well-equipped infrastructure facility has enabled us to manufacture, export and supply high-grade Calcium Carbonate. The offered compounds are mainly used as an extender in paints and as a filler in plastics. Supreme grade natural compounds are obtained from the well-known mines to process these into fine materials. These compounds are processed in our huge infrastructure facility by removing all the removing all the impurities and other unwanted elements. To meet the diverse requirements of our clients, we offer the Calcium Carbonate in many packaging sizes.

Calcium Carbonate is a chemical compound with the chemical formula CaCO3. It is a common substance found in rocks in all parts of the world.

 

The vast majority of calcium carbonate used in the world is extracted by mining or quarrying. Alternatively, calcium carbonate is prepared by calcining crude calcium oxide.

 

PCC is used in applications that demand exacting specifications of particle size, particle size distribution and physical colour. The activation of Stearic Acid is carried out on CaCO3 for specific requirements.

 

Calcium carbonate is widely used as an extender in paints, in particular matt emulsion paint.

 

Calcium carbonate is also widely used as a filler in plastics. Some typical examples include loading of chalk in un plasticized polyvinyl chloride (uPVC) drain pipe and loading of stearate coated chalk or marble in uPVC window profile. PVC cables also use loading to improve mechanical properties (tensile strength and elongation) and electrical properties (volume resistivity). Polypropylene compounds are often filled with calcium carbonate to increase rigidity, a requirement that becomes important at high use temperatures.
