Hydrophobic precipiated silica(white carbon black) with rheological adjustment ability
Hydrophobic precipitated silica( white carbon black ) use the hydrophobic organic modifier to modify on the surface of the silica and obtains organic - inorganic hybrid materials. It has high surface activity, low hygroscopicity, good organic dispersity and excellent polymer compatibility.
Even for the polar system it also has rheological adjustment ability, in some rubber products with transparent, translucent nature. In addition, some silica products can be helpful for customers to develop new products and improve product performance after the hydrophobic treatment on the basis of structural modification.
