What is PCC?Find a Product Mineral Technologies Latest News

Precipitated calcium carbonates (PCCs) make your paper white, your vinyl windows and siding tough, and your bones strong. Talcs protect your car bumpers from damage, your house paints from weathering, and your baby’s tender skin from chafing. Ground calcium carbonates (GCCs) make stuccos bright, roof shingles durable, and chewing gums chewy. PCCs and GCCs come from the mines and processing plants of Specialty Minerals Inc. (SMI).
