Precipitated silica

While carbon black, chemistry name "silicon dioxide" , main ingredient "sio2", similar to carbon black in the application , appearance showed white , highly dispersed , amorphous powder or flocculent powder.


Main application:
White carbon black is widely used as reinforcing agent for rubber and plastic , thickening agent for ink , additives for coating , and paint , flatting agent for leather , dispersing agents for insecticides , fillers for manufacturing papers , additives for resin , fillers for insulating and thermal insulation materials . Meanwhile , it is also used as open agent for polyethylene film and carriers, anti caking agent for food , pesticide and medicine.

Natural Silica (chemical name for the mineral quartz and a synonym for silicon dioxide) Silica is a compound of the elements silicon and oxygen. It is not chemically combined with other elements. When the basic structure of the molecule is a pattern that is repeated and symmetrical, the silica is considered to be "crystalline." Silica is considered to be amorphous if the molecule lacks crystalline structure. In this brochure, the term silica is used to mean crystalline silica (or crystalline silica's most common form, quartz).

Used in manufacture of special steels and cast iron, aluminum alloys, glass and refractory materials, ceramics, abrasives, water filtration, component of hydraulic cements, filler in cosmetics, pharmaceuticals, paper, insecticides, rubber reinforcing agent - especially for high adhesion to textiles, anti-caking agent in foods, flatting agent in paints, thermal insulator. Fused silica is used as an ablative material in rocket engines, spacecraft, silica fibers used in reinforced plastics.

Available in Micro silica, Fused Silica, Amorphous Silica, Precipitated silica, Quartz powder different mesh sizes and fine powder as per requirement.

Packing: Standard 25kg. HDPE wove sack or paper bag.
