Anwendungen & Verwendung
Verwenden
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.
