Hydrophobic silicon dioxide (silica)    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. in                                                      

Application : Silicon Rubber, antifoaming agent, resin.
