Home - Precipitated Calcium Carbonate Product Portfolio | RBH Ltd Precipitated Calcium Carbonate High purity precipitated calcium carbonate (PCC) functional mineral with controlled particle size and surface properties for coatings, polymers, paper, adhesives and speciality applications. CAS NUMBER: 471-34-1 Request A Sample Names Precipitated Calcium Carbonate|PCC|Calcium Carbonate Chemical formula CaCO₃ Product Overview Precipitated Calcium Carbonate (PCC) is a high purity, synthetically produced calcium carbonate functional mineral engineered for consistent particle size, controlled surface characteristics and tailored performance across coatings, polymers, rubber and speciality applications. Produced by reacting lime with carbon dioxide under controlled conditions, PCC delivers extremely low levels of impurities, narrow particle size distribution and high brightness, making it suitable for demanding formulation requirements. The controlled precipitation process allows PCC grades to be tailored to specific performance goals, including impact on rheology, opacity, gloss, surface smoothness and dispersion behaviour. In coatings and inks, PCC improves brightness, opacity, rheological balance and pigment loadings. In plastics and thermoplastics, PCC functions as a cost-effective filler offering stiffness, dimensional control and surface finish. Specialty grades support adhesives, sealants, construction compounds and rubber systems where controlled mineral interaction aids processing and performance. PCC’s versatility as a filler and functional mineral is enhanced by its high purity, low contaminant profile and predictable processing behaviour, giving formulators flexibility to optimise performance across multiple industrial sectors.
