Calcium Carbonate for Foot Wear Industry
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 reinforcing filler in Rubber Industry such as a Tyre/Tubes, Slipper Soles, Floor Mats & Conveyor Belts. It improves strength as well as whiteness. It imparts stiffness to non- cured rubber products.
