Hydrophobic precipitated silica
As a mixed organic-inorganic material hydrophobized with organic dressing agent in the precipitated solution, the hydrophobic precipitated silica we produce has the following characteristics: high surface activity, low hygroscopicity, enhanced dispersibility in organic medium and excellent polymer compatibility. And it also has the rheological capability to adjust the polar system, add the transparent/semi-transparent characteristics for rubber products.
