What is Ground Calcium Carbonate (GCC)?
Ground Calcium Carbonate (GCC) is a naturally occurring mineral obtained from limestone, chalk or marble. It is processed into a fine powder and used in numerous industrial applications. In plastic production, GCC acts as a reinforcing filler, improving product performance and reducing material costs. Unlike Precipitated Calcium Carbonate (PCC), which is synthetically processed, GCC is directly ground from natural limestone, offering a cost-effective and eco-friendly solution.
