Resistance to high temperature, no combustion, good insulation, odourless propertiesApplication1. White Carbon Black (Silicon Dioxide, Hydrated Silica) are a versatile inorganic chemical which are used for reinforcement of rubbers and plastics, coating and paints, printing inks and cosmetics, antiblocking of plastic foils, free running and free flow of sticky solid and liquid substances, carrier for pesticides, insecticides, high temperature insulation, stabilizing of beer and silicon rubber.2.White Carbon Black(Silicon Dioxide, Hydrated Silica) possesses a high reinforcing potential and imparts to rubber compounds particularly high Shore hardness, tensile strength, tear resistance and abrasion resistance. In order to achieve optimum rubber-technical data the addition of activators like glycols, amines or other alkaline accelerators is necessary.Fumed silica powder (Fumed silica powder)Productive Process:Fumed Silica is produced with the method of gas phase . Its theory is burning the chloride under oxyhydrogen flame and high- temperature vapor phase hydrolysis, and collected finished product after refining process of condensation, separation, deacidification and screening.Application Features:1.Thickening and thyrotrophic effect2.Suspension and emulsification3.Free-flowing and anti-caking4.Anti-slipping function5.Extinction effect6.Anti-adhesion effect7.Enhancing reinforcement effectTech Data(Precipitated Silicon SiO2)IndexSpecificationAppearanceFine White Powder/GranularSiO2,%98minLoss on drying at 105 DC,%3.0-6.0Loss on Ignition at 1050 DC ,%4.0-6.0PH value:6.0-6.8Bet surface area, m2/g170-200DBP oil absorption,ml/100g280-300Sieve residue on 325mesh,%5.0maxTapped density, g/l200-250Soluble Salts content,%3.5max
