Description and Uses

It can improve the properties of the mineral-filled elastomer, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience. It can be used as a pretreatment on minerals or added at the time of compounding. Mineral-reinforced rubbers such as shoe soles, rollers, wheels, white sidewalls, wire and cable insulation are the common case (3-Mercaptopropyl)triethoxysilane, could be used in. It also finds it uses as an intermediate, in polymer and tire manufacture, and as a laboratory reagent.
