Ground Calcium Carbonate (GCC) is extensively used in the rubber industry as a reinforcing filler and cost-effective extender. It improves the mechanical properties of rubber products such as tensile strength, hardness, and abrasion resistance. GCC also enhances processing efficiency by improving the compound’s viscosity and flow during manufacturing. Its high purity and fine particle size help produce rubber with a smooth surface finish and consistent quality. By partially replacing more expensive fillers like carbon black, GCC contributes to reducing production costs while maintaining excellent performance in a wide range of rubber applications, including tires, seals, and hoses..
