Precipitated Hydrophobic silica

Precipitated Hydrophobic silica ( White Carbon , SiO2 ) Una.700 It mainly will generally get close to water sex Silion dioxide under the condition of appropriate with alkane of silion accidentally the join responds but becomes, make a kind of surface has the solid powder form that the silion oxygen alkane( polysiloxane) connects of gather two oxidize the silion , its hydrophobe contacts Cape can amount to 70-150, not only have the good hydrophobe at the same time but also eliminate to steep the function, applicably in the spinning dying, eliminate to steep the , lubricant, not saturated polyester resin, powder to extinguish fire the products, such as and the silion rubber...etc. inApplication : Silicon Rubber, Antifoaming agent, ResinTechnique IndexItemIndexAppearancesuperfine white powderSiO2 %≥98.0PH (5%aq.suspension)6.8-7.1BET Surface Area m2/g200-220Oil Absorption ml/g2.0-3.5Loss on drying(105oC) %≤6.0Loss on Ignition(1000oC) %≤7.0Iron mg/kg≤1000Na2SO4 Content %≤0.5Partical Size μm3-5Packing kg/bag10
