• Uses: Bis[3-(triethoxysilyl)propyl]tetrasulfide is a silylating coupling agent and modifier, and has been used in the design of a new generation of sustainable self-healing styrene-butadiene compounds. Bis[3-(triethoxysilyl)propyl]tetrasulfide is used in radial tires, rubber tire treads, carcass, tire walls, solid rubber tires and other rubber products. It acts as a chemical intermediate and as a cross linking agent. Furthermore, it acts as a coupling agent used to chemically modify silica surface. In addition, it serves as a curing agent for good heat aging. Bis[3-(triethoxysilyl)propyl] tetrasulfide (TESPTS) is generally used as a crosslinking agent and reinforcing filler in the manufacturing of rubber. TESPT film provides corrosion protection to the metallic substrates. It is also used as a precursor in the synthesis of mesoporous organosilicas.
