Calcite Powder (GCC – Ground Calcium Carbonate) in PVC Manufacturing: A Complete Guide
Introduction
In modern PVC manufacturing, raw materials are not just about cost — they’re about performance, consistency, and sustainability. One of the most critical ingredients for PVC product manufacturers today is Calcite Powder (GCC – Ground Calcium Carbonate). This versatile, natural mineral filler is widely used in the production of PVC pipes, cables, profiles, sheets, and other plastic components.
At Keshav Madhav Mineral Industries, we produce high-purity Calcite Powder (GCC – Ground Calcium Carbonate) designed to meet the demanding specifications of industrial applications. Our material is known for its brightness, whiteness, fine particle distribution, and excellent blending ability with polymer resins.

What is Calcite Powder (GCC – Ground Calcium Carbonate)?
Calcite Powder is the micronized form of natural calcium carbonate, primarily obtained from high-purity calcite stone. When produced through mechanical grinding and without chemical processing, it is referred to as GCC – Ground Calcium Carbonate.
This natural filler is widely appreciated in the plastic and polymer industries for:
High brightness and whiteness
Controlled particle size
Excellent dispersion in polymer matrices
Low moisture and oil absorption
