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 filler ain PVC Pipe Industry. In PVC Pipes, such as vinyl siding and fencing, PCC increases impact strength, gloss tensile strength, elongation etc. with some of the smaller particles able to replace expensive impact modifiers. These are special grades for high percentage filler loading in PVC Pipes.
