Types of Calcium Carbonate Powder
Ground Calcium Carbonate
GCC Powder is produced by mechanically grinding natural limestone, marble, or chalk into a fine powder. It is the most widely used form of Calcium Carbonate Powder, commonly applied in paints, plastics, construction materials, and as an animal feed additive. Calcite Powder falls under this category and is known for its cost-effectiveness and consistent particle distribution.
Precipitated Calcium Carbonate
Precipitated Calcium Carbonate is manufactured through a controlled chemical process reacting calcium oxide with carbon dioxide resulting in a purer, finer product compared to GCC. PCC Powder offers tighter control over particle size and higher brightness, making it suitable for high-end applications in pharmaceuticals, cosmetics, paper, and food processing.
Activated Calcium Carbonate
Activated Calcium Carbonate is produced by coating Precipitated Calcium Carbonate slurry with fatty acids (typically stearic acid) and a coupling agent. The treated powder offers improved dispersibility and compatibility with polymers, making it ideal for rubber and plastic applications where enhanced performance is required.
Coated Calcium Carbonate
Coated Calcium Carbonate Powder is treated with a thin layer of stearic acid or other fatty acids, making it hydrophobic. This surface treatment improves flow in non-aqueous systems and reduces moisture absorption, which is why it is widely preferred in plastics, rubber, and composite material manufacturing.

Key Applications of Calcium Carbonate Powder
Paint Industry
Calcium Carbonate Powder is widely used in the paint industry as an extender and filler. It improves opacity, enhances brightness, and helps achieve the right viscosity.
For Paper & Printing Industry
In the paper and printing industry, GCC Powder and PCC Powder serve as coating pigments and fillers that improve paper smoothness, brightness, and printability.
For cables Industry
Calcium Carbonate Powder is used as a functional filler in cable insulation and jacketing compounds. It improves flame retardancy, and reduces smoke emission.
For pipes & PVC products
The PVC pipe industry uses Calcite Powder extensively as a filler that improves rigidity, dimensional stability, and processability without compromising product performance.
For Non Woven Fabric Industry
In the non-woven fabric sector, Calcium Carbonate Powder acts as a mineral filler that improves the stiffness and uniformity of the fabric.
For Film Industry
In plastic film manufacturing, Calcium Carbonate Powder is used as a filler that improves film stiffness, reduces material costs, and helps control light diffusion.
For Rubber Industry
Calcium Carbonate Powder is used in rubber compounding to enhance tensile strength, hardness, and elongation.
For Adhesives Industry
Calcium Carbonate Powder serves as a rheology modifier and filler in sealants, adhesives, and mastics.
