Application

Precipitated silica Felcosil-175GR is made as a semi-reinforcing filler in non-black SBR compounds.

White Carbon Black Granular Felcosil-175GR has excellent reinforcement performance and surface activity in white and light-colored fillers and is widely used in rubber soles, tires, rubber pipes, rubber tapes, cost, rubber seals and other products.

Felcosil-175GR produced an improvement in the wear resistance of these compounds. The formulas, based on a combination of SBR, silica, and high styrene resin, provided hitherto unavailable levels of abrasion and tear resistance.

These benefits, together with the elimination of the floor marking deficiency of black soles, led to the gradual replacement of carbon black and clay in both hard and soft soling.

Beyond the selling and footwear markets, silica's adaptability to compounding in color made it a valuable new resource in belting, hose, and other mechanical goods products.
