Product Description

Rubber Additive Bis[3-(Triethoxysilyl)Propyl]Tetrasulfide CAS 40372-72-3

Bis(triethoxysilylpropyl)tetrasulfide is an organosulfur compound with the formula S4[C3H6Si(OEt)3]2 (Et = C2H5). The molecule consists of two trialkoxysilyl propyl groups linked with a polysulfide. It is often sold as a mixture with the trisulfide. The compound is a colorless viscous liquid that is soluble in ordinary organic solvents such as toluene. Commercial samples often are yellowish. The compound is added to rubber compositions that contain silica filler.
