Calcium Carbonate
Processed through controlled grinding to achieve ultrafine particle distributions, available in coated and uncoated grades for brightness, opacity, dimensional stability, and dispersion across plastics and paints.
Product Overview: Micronized Calcium Carbonate
Calcium Carbonate is processed through controlled grinding and classification to achieve ultrafine to nano-sized particle distributions. Offered in both coated and uncoated grades, it serves a broad range of industrial systems including plastics, paints, polymers, rubber, adhesives, and construction chemicals.
Its high brightness, chemical purity, and tailored particle characteristics support opacity, surface smoothness, dimensional stability, and efficient processing. Uncoated grades provide cost-effective filling, bulk, and brightness in water-based coatings, while stearic acid coated grades offer improved hydrophobicity, polymer compatibility, reduced plasticizer absorption, and superior dispersion in non-polar systems.
