We are one of the leading Suctions of Precipitated Silica today, having complete vertical integration, rigid quality control standards and unique product properties. We have developed products with unmatched properties, by standards. We cater to every segment of the market with user specific products. We are the global leaders today in the manufacture of precipitated calcium silicates having following unique properties :

Very High Water/Oil Absorption : Up to 600 % has been achieved and efforts are in progress to achieve the 800% mark. Most competing products have water-absorption up to 300% maximum only
Very Low Bulk Densities : Up to 0.04 gm/cc has been achieved
Very High Surface Areas : Up to 600 m2/gm has been achieved

Applications Of Precipitated Silica
Precipitated Silica having high absorption capacities can be used to provide one or several of the following properties :

Free-Flow
Ant caking
Reinforcement
Rheology Control
Thixotropy
Flatting
Insulation
Suspension
Carrying Agent
Matting
Lightness
Inert Filler

Pesticides

For improvement in the suspension power and as a carrier for the active Ingredients, specially malathion, acephate and iso-proton based formulations
For improvement of free-flow characteristics and storage stability
As a grinding auxiliary

Feedstuffs And Food Items

Improvement in free-flow properties and storage stability of table salt, spices etc
Anti-caking of milk extenders and fat concentrates, feedstuff urea & mineral Mixtures
Conversion of 75% aqueous chloride solution into stable 50% powder form
Conversion of liquid active substances into powder form, e.g. Ethoxyquin, flavors & fragrances

Chemicals

Conversion of liquids to free flowing powder form (e.g. SP antioxidant & other rubber chemicals)
As a grinding additive (e.g. With sulphur)
For anti-caking & free flow

Plastics And Polymers

To provide reinforcement properties in PP, PVC, PE and Polystyrene based master batches
As an anti-blocking agent in blown films & foils
With Phenol + melamine resins for anti-caking during storage and improvement in dosing properties of molding compounds
Auxiliary during production of polychloroprene based adhesives
With thermoplastic rubber for reduction in abrasion and increase in dimensional heat stability
Reinforcement of Natural, SBR, Silicone, EVA, Nitrile, EPDM & other rubbers

Other Products

Liquid Systems : Due to high surface area they function as clarifying and adsorption agents (e.g. beverages)
Adhesives : To adjust rheology and provide reinforcement
Greases/Lubricants : For rheology control
Paint, Dyes & Printing Inks : As a flatting/matting agent to reduce gloss or as filler
Paper Industry : Provides lightness, whiteness & improves mechanical properties
Toothpaste & Polishes : As a mild abrasive and for rheology control
Pharmaceuticals : As a processing aid in tabletting & pelletizing
Cosmetics : For rheology control

Precipitated Silica
Precipitated Silica is available in various combinations of physical properties such primary and secondary particle size, surface area, bulk density absorption capacity etc. It is available in three physical form categories :
