Hydrophobic SiO2 Nanopowder for Industrial Applications | JK SILICA
Speciality Silica
Hydrophobic Silica JS-681/682
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.
Applications of hydrophobic precipitated silica
Rheological agent: separant for emulsion, anti-settling agent for paints/coatings/inks/toners, thickening agent, thixotropic agent, anti-block agent for plastic film;
Powder glidant: for powder extinguishing agent and powder coats;
Granula agent and dispersion agent for pesticides;
Carrier for explosive;
Thickening agent for Adhesives and various kinds of polar liquid like epoxy resin;
Defoaming agent:
Abrasive agent for tooth paste;
Reinforcing agent for organic silica elastomer;
With the hydrophobic and anti-corrosion characteristics, the hydrophobic precipitated silica can also enhance the insulating property for cables and cords. And with the high reinforcement, the hydrophobic precipitated silica is widely used in the industrial plastic, modified plastic and silicon rubber.
