Coated Calcium Carbonate

About Coated Calcium Carbonate

Coated Calcium Carbonate is specially processed with a surface treatment, typically stearic acid, to enhance its dispersion, compatibility, and performance in polymer-based applications. This unique coating makes it highly effective in improving impact resistance, processing speed, and surface smoothness in PVC, PE, PP, and other plastic compounds. It reduces moisture absorption, enhances flow properties, and minimizes wear on processing equipment. In addition, Coated Calcium Carbonate improves gloss and finish in films, pipes, profiles, and sheets, while lowering overall production costs by replacing expensive raw materials. It is also widely used in adhesives, paints, and sealants for superior rheology and stability. Due to its hydrophobic surface, it bonds better with polymer matrices, providing stronger mechanical strength and thermal stability. Our Coated Calcium Carbonate is sourced from premium reserves and processed under strict quality controls to ensure consistent particle size, high purity, and excellent performance across industries.
