Hydrophobic silica

Hydrophobic silica ( white carbon , SiO2 ) Una.700 Una.700mainly 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. in.Packing: PP/woven bag, EVA/woven bag, kraft paper bag Application : Silicon rubber, antifoaming agent, resin Technique Index Item Index appearance superfine white powder SiO2%≥98.0 PH (5%aq.suspension) 6.5-7.5 BET Surface Area m2/g≥220 Oil Absorption ml/g2.0-3.5 Loss on drying(105oC)≤6.0 Loss on Ignition(1000oC)≤7.0 Iron mg/kg ≤1000 Na2SO4 Content % ≤0.5 Partical Size μm 3-5μm Packing kg/bag10kg
