Precipitated Calcium Carbonate ( PCC ) is an innovative product derived from lime stone, which has many industrial applications. PCC is made by hydrating high- calcium quick lime and then reacting the resulting lime slurry with carbon dioxide. The resulting product is extremely white and typical has a uniform narrow particle size distribution. PCC is available in numerous crystal morphologies and sizes, which can be tailored to optimize performance in a specified application.
Precipitated Calcium Carbonate is used as a rheology modifier in Adhesive & Sealant Industry in a variety of sealants formulation such as PVC Plastisols, Polyurethane, MS polymers, Polysulphide epoxy and as a chemical additive to add properties the most notable being thixotropy. It has Aragonite structure with different particle size distribution and apparent densities.
