Activated Precipitated Calcium Carbonate CaCO3 CAS 471-34-1
CAS No. 471-34-1 EINECS: 207-439-9
Formula: CaCO3 Appearance: white crystals or powder
Chemical Properties:
Industrial Active Precipitated Calcium Carbonate (Active Light Calcium Carbonate): This product is produced using the wet method and involves surface activation treatment of light calcium carbonate with stearic acid, active agents, and coupling agents. The active light calcium carbonate is a fine white powder with its particles' surfaces coated by active substances, which ensures good dispersion in polymer matrices.
