Calcium Carbonate for Ink Industry
Description:
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.
Application:
Precipitated Calcium Carbonate is used as an extender and opacifying agents in INK industry such as Printing Ink to control stability and imparts brightness. It has Aragonite structure with different particle size distribution and apparent densities.
