Precipitated Calcium Carbonate Powder

Precipitated Calcium Carbonate (PCC) is chemically similar to other forms of CaCO3 such as limestone, marble and chalk. Like other forms of Calcium Carbonate, PCC is also considered to be non-toxic. Only difference is in the purity, where PCC is purer than other forms and has lower content of silica and lead.

Product Uses

Paper Industry

PCC is a well-known filler and coating pigment for high-end paper goods. Through the replacement of more expensive pulp fibre and optical brightening chemicals, PCC improves the optical qualities and print characteristics of paper products, increases the productivity of paper machines, and can lower the cost of producing paper

Polymer Industry

Due to its capacity to produce small particle sizes and unique crystal forms, PCC also has a wide range of industrial applications. PCC boosts impact resistance in rigid polyvinyl chloride (PVC), such as vinyl siding and fencing, with some of the smaller particles being able to take the place of pricey impact modifiers.

Automotive and Construction

The viscosity and sag of automotive and construction sealants like PVC plastisols, polysulfides, urethanes, and silicones are controlled by nano PCCs (less than 0.1 micron in size).

Paint Industry

Due to its pigment dispersion properties, PCC is employed and valued for lowering doses and costs in finished formulations. Precipitated calcium carbonate is the major pigment extender used in paint to reduce the doses of expensive titanium dioxide (TiO2) and to add opacity and brightness.


PCC is a common ingredient in calcium-based antacid pills and drinks because it is an efficient acid neutralizer. PCC's high calcium content makes it possible to formulate tablets with many vitamins and minerals and calcium supplements at large dosages. The creation of tasty calcium-fortified meals and beverages is aided by the small particle sizes and unique particle shapes.
