Hydrophobic silica ( white carbon , SiO2 )     Una.700                        

Una.700 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. in.           

Packing: PP/woven bag, EVA/woven bag,  kraft paper bag
