Precipitated Silica as a kind of environmental protection, excellent agents, mainly used for rubber products (including high temperature vulcanization silicone rubber), textile, paper making, pesticide, food additive field. Precipitated silica has strong adhesion strength, tear resistance and heat-resistant anti-aging performance, so can replace part of the carbon black in the black rubber products, in order to obtain high quality rubber products, such as off-road tires, otr tires, radial tire, etc.
In addition It can also be used in fire fighting agent, feed, cosmetics, flatting agent, paint, paint and many other industries.
