What is the Difference Between GCC and PCC Calcium Carbonate?
Calcium carbonate, a critical industrial filler, exists in two primary forms: GCC (Ground Calcium Carbonate) and PCC (Precipitated Calcium Carbonate). GCC is mechanically ground from natural limestone or marble, offering cost-effective bulk filling for plastics, rubber, and paper. PCC is chemically synthesized, providing finer particles, higher brightness, and enhanced mechanical properties for premium applications like coatings and adhesives.
