Heavy Calcium Carbonate, commonly known as Ground Calcium Carbonate (GCC), is produced by grinding and processing naturally occurring calcium carbonate minerals such as limestone, marble, or calcite into a fine powder.

Due to its high mineral content, whiteness, particle-size availability, and cost-effectiveness, Heavy Calcium Carbonate is widely used as a filler and functional additive in a broad range of industrial products. It can help improve bulk, stiffness, opacity, surface characteristics, and processing economics while reducing the overall cost of formulations.

In the plastic and PVC industry, Calcium Carbonate is commonly used as a mineral filler in products such as PVC pipes, profiles, sheets, films, cables, plastic masterbatch, and various molded products. The appropriate particle size and surface treatment depend on the polymer system and required mechanical properties.

In the paint and coating industry, it can function as an extender and filler, contributing to opacity, coverage, texture, and formulation economics. It is also widely used in rubber, adhesives, sealants, paper, construction materials, putty, tile adhesives, and other industrial formulations.

Heavy Calcium Carbonate is available in different particle sizes, whiteness levels, moisture contents, and purity grades. Therefore, the correct grade should be selected according to the intended application.
