Calcium Carbonate
Calcium Carbonate
Calcium Carbonate is a naturally occurring mineral produced by finely grinding high-purity limestone or marble.
It is a cost-effective, high-brightness functional filler widely used in numerous industries to improve product performance, processing, and overall quality. GCC is available in various particle sizes and grades to suit specific industrial applications.
Applications
Paints & Coatings
Calcium Carbonate improves opacity, brightness, scrub resistance, and durability while reducing formulation cost. It also enhances rheology, smoothness, and overall coating performance.
Paper Industry
Calcium Carbonate is used as a filler and coating pigment to improve paper brightness, whiteness, smoothness, printability, and opacity. It also reduces production costs by replacing a portion of expensive pulp.
Ceramic Industry
In ceramic formulations, Calcium Carbonate acts as a source of calcium oxide during firing, improving strength, dimensional stability, and surface finish. It is widely used in wall tiles, floor tiles, sanitaryware, and ceramic bodies.
Plastic Industry
Calcium Carbonate is extensively used as a functional filler in PVC, PP, PE, masterbatches, and engineering plastics. It increases stiffness, dimensional stability, impact resistance, and processability while reducing raw material costs.
Rubber Industry
Calcium Carbonate is used as a reinforcing and extending filler in natural and synthetic rubber compounds. It improves tensile strength, hardness, abrasion resistance, surface finish, and processing efficiency while lowering production costs.
