Granular Precipitated Silica Application

Felcosil-185GR is mainly used in Shoe outsole, rubber rice roller and Tyre industries. It is so low dust, high bulk specific weight that it can be easy to process.

Felcosil-185GR Silica in rubber industry, Precipitated Silica 185GR with its superior reinforcement and transparency in the first place.

In resin matrix composites, Precipitated Silica 185GR can be dispersed fully and evenly into resin materials, so that the strength, toughness and ductility of epoxy resin are greatly improved, and the wear resistance and material surface finish are improved, and the aging resistance is improved.

If precipitated Silica Felcosil-185GR is added to the ordinary rubber, the strength, wear resistance and aging resistance of the product will reach or exceed the top-grade rubber products, and the color will remain unchanged for a long time.
