Precipitated Silica

The company provides the best quality Precipitated Silica for various industrial applications. Precipitated Amorphous Silica has high surface area and Oil/ Water Absorption with low bulk density. Apart from that, we are one of the major Biochemically Precipitated Silica Suppliers in India. We are the global leaders today in the manufacture of precipitated calcium silicates having following unique properties: Very High Water / Oil Absorption : Upto 600% has been achieved and efforts are in progress to achieve the 800% mark. Most competing products have water-absorption upto 300% maximum only. Very Low Bulk Densities : Upto 0.04 gm/cc has been achieved whereas competing products have 0.12 gm/cc minimum. Very High Surface Areas : Upto 600 m2/gm has been achieved. PRODUCTION FACILITIES Precipitation is carried out in microprocessor controlled batch reaction vessels, followed by filler-presses/vaccum filters and flash/spray driers and finally micro-mill with classifier for micronization wherever required.
