Hydrophilic Fumed Silica A.Characteristic: It is a white and colloidal micro-particle with its primary micro-particle from 5-40 nm and has obvious properties such as thixotropy, reinforcing, thickening and filling etc. and is insoluble in all kinds of solvents and liquids except hydrofluoric acid and concentrated bases. It is used widely in silicon rubber, construction sealant, coating, electron and electric, aerospace, medicine and medical material, resin processing, printing ink, pesticide and other industries. F-150: used widely in silicone acid rubber, sulfurized silicone rubber in ambient temperature (low water content), silicone neutral rubber. F-200: used widely in sealing ring, sealing gasket, petroleum pipeline, insulator, tablet powdered preparation, artificial viscera, infusion tube, latex nipple and high quality oil ink. F-380: used widely in reinforcing agent for silicone rubber, medical silicone rubber for transparent artificial organs and artificial heart etc. Packing: packed with multi-layer paper plastic compound bag with net weight of 5 kg or 10 kg, or packed by whole plastic seal for users having special demand on water content. 10kg per bag

Meanwhile , it is also used as open agent for polyethylene film and carriers, anti caking agent for food , pesticide and medicine. Package: 20kg or 10kg/ woven bag Package: 20kg or 10kg/ woven bag
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. 25kg, 50kg, 980kgs.Junbo packs.
