Precipitated Silica is As an active filler, silica replaced carbon black reinforcing effect in rubber products, which can improve the mechanical properties of rubber products, abrasion resistance, and thermal properties of oil-resistant rubber products. It can also improve the tensile strength, tear strength, abrasion resistance and flexibility of rubber products and tires. Different rubber and tire compounds should choose to use a different type of silica in order to obtain expected performance.
