Fumed silica is the superfine micro-nano fine chemical product , which is divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments, its appearance is white powder , native particle size ranges from 5nm to 40nm, with signficant functions of thixotropy, reinforcing, thickening and filling. it is widely used in the industries of rubber , sealant, plastic , resin, paint, printing ink, papermaking, medicine, cosmetics food etc.
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

Due to the unique features of small particle size, large specific surface area and highly active surface, fumed silica is widely applied in silicon rubber, paint, adhesive, printing ink, plastic, comestic, agriculture and pharmacy. It's functions include reinforcement, thickening, thixotropy, extinction, sterilization, anti-uv light and etc. 10kg/bag, 20bags/pallet
Features Of Micro Silica (Silica Fume) Micro Silica also known as Silica fume. It is a by product of producing silicon metal or ferrosilicon alloys in smelter using electric arc furnaces. It is a grey coloured powder, pozzolanic in nature. Applications Concrete Industry Refractory Rubber Industry Anti caking agent Pellet Binder
Microsilica (silica fume) is a by-product of silicon metal or ferrosilicon industries, is an amorphous silicon dioxide SiO2. This product reacts chemically with the calcium hydroxide in the cement paste which yields a calcium silicate hydrate gel that significantly enhances strength and durability. The super fine microsilica fills the voids between cement particles creating a very dense, less permeable concrete. Physical characteristics: Color: gray or gray white powder Bulk density: 320-700 kg/m3 Chemical composition: Items SiO2 Al2O3 Fe2O3 MgO CaO Na2O Moisture Content 75-98% 1.0-0.2% 0.9-0.3% 0.7-0.1% 0.3-0.1% 1.3-0.2% Fineness: the fineness of the silica fume is less than 1 1/4m, and the average particle size is 0.1 0.3 1/4m, and the specific surface area is 20 - 28 m2/g. The fineness and specific surface area are about 80-100 times of cement and 50-70 times of fly ash. Maxtech Micro Silica supplies will be as per QCS 2014 (ASTM C1240): SiO2: >/= 92% LOI:
