Precipitated Silica for the Rubber Industry
Precipitated silica, as excellent filler and reinforce agent, is widely used in rubber and tire industry. It plays an essential role in reinforcement, which could replace the function of carbon black and provides rubber with high strength and durability. Further, it could improve the mechanical properties of rubber products, like tensile strength and elongation. JS-185GR of precipitated silica are designed for different market demand. This products are mainly applied in rubber industry.
