Ground Calcium Carbonate
Ground Calcium Carbonate (GCC) is produced by grinding naturally occurring calcium carbonate. It is widely used as a functional filler in plastics, paints, rubber, and paper due to its high brightness, low oil absorption, and excellent dispersion properties.
Applications
- Plastic and polymer industry
- Paints and coatings
- Rubber industry
- Paper manufacturing
- Adhesives and sealants
Properties
- High brightness and purity
- Low oil absorption
- Excellent dispersion
- Stable chemical composition
- Fine particle size distribution

Frequently Asked Questions
GCC (Ground Calcium Carbonate): Naturally mined and ground, more cost-effective, variable particle shapes
PCC (Precipitated Calcium Carbonate): Chemically synthesized, uniform particle shapes, higher purity but more expensive
PCC (Precipitated Calcium Carbonate): Chemically synthesized, uniform particle shapes, higher purity but more expensive
Paper manufacturing (40-50% of global usage), plastics (25-30%), paints & coatings (15-20%), and construction materials are the largest consumers of GCC.
Smaller particles (800-1500 mesh) provide smoother finishes and better opacity, while larger particles (200-400 mesh) offer better bulk and cost-effectiveness for structural applications.
Our GCC offers consistent quality, controlled particle size distribution, low moisture content, and excellent brightness. We source from premium deposits and maintain strict quality control throughout processing.
