Ground Calcium Carbonate GCC

1. Product Overview

Ground Calcium Carbonate (GCC) is a finely processed, high-purity mineral derived from naturally occurring limestone or calcite. It is widely used as a functional filler and performance-enhancing raw material across plastics, paints, coatings, paper, rubber, construction materials, and adhesives. GCC delivers excellent whiteness, controlled particle size, and cost efficiency while improving product performance and reducing formulation costs. Its broad industrial applicability makes it a strategically important mineral for reliable, large-scale manufacturing and sourcing.
