Ground Calcium Carbonate (GCC) is widely used in the plastic industry as a functional filler to enhance the physical and mechanical properties of plastic products. It improves stiffness, impact resistance, and dimensional stability while reducing production costs by partially replacing expensive polymers. GCC also contributes to better heat resistance and surface finish, making plastics more durable and visually appealing. Its fine particle size allows easy dispersion within plastic matrices, supporting efficient processing and improving the final product’s quality. GCC is commonly used in applications such as packaging, pipes, automotive parts, and household goods.
