Calcium carbonate in the form of chalk, whiting, and limestone is perhaps the most widely available and utilised mineral in the world additives today. Processed to be available in a wide range of particle sizes, the products function as low cost fillers added to extend and cheapen the widest range of polymeric systems.
In comparison to this, synthetic PCC offer a range of technical effects beyond the capability of GCC fillers and other more expensive and sophisticated additives. Precipitated Calcium Carbonates (PCC) are characterised by the following important attributes:
The combination of these properties clearly differentiates PCC from GCC fillers and is also a factor in explaining the performance effects that are observed during the use of the precipitated products in several application .
The manufacturing of precipitated calcium carbonate by the reaction of gaseous carbon dioxide with a colloidal suspension of calcium hydroxide is sufficiently versatile to allow a number of different morphologies to be developed. Distinctive and reliable reaction control criteria exist for the manufacture of PCC where morphology and crystalline size can be varied at will.
The resultant PCC further surface modified by several sterates and coupling agents so as to provide an excellent compatibility as well as a better bonding with the polymeric resins
Our uncoated and coated PCC is widely used globally in PVC Pipe , Fittings , Profiles & Cable Application , Rubber Application , Sealant & Adhesives , SMC / DMC Application , Paper , Paint , Printing Ink , Pharmaceutical & Food Application , Dentrifices & Cosmetics Industry .
