Description

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. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
