What is Calcium Carbonate Powder?
Calcium carbonate (CaCO₃) is a natural mineral found in limestone, chalk and marble. It is processed into a fine powder that is widely used in various industrial applications, including paint and coatings. There are two main types of calcium carbonate:
- Ground Calcium Carbonate (GCC) – Derived from natural sources and mechanically processed to achieve different particle sizes.
- Treated (Coated) Calcium Carbonate with Stearic Acid and other lubricants for Plastic Industry Applications, Pvc pipes & Fittings, Filler MasterBatch.
- Precipitated Calcium Carbonate (PCC) – Synthetically produced with controlled particle sizes and higher purity, offering specific benefits for coatings.
Calcium carbonate is widely used in the paint and coatings industry due to its ability to improve performance, cost-effectiveness and sustainability. Read More Ground calcium carbonate powder for plastic filler
