Product Code:SP8032

Product Name:Bis[3-(triethoxysilyl)propyl]disulfide

Product Introduction:

Bis[3-(triethoxysilyl)propyl]disulfide is a sulfur-containing silane coupling agent. It features a cleavable disulfide bond that enhances rubber-to-filler adhesion, particularly in silica-reinforced tire compounds. It improves mechanical properties and reduces rolling resistance by controlled filler dispersion and polymer coupling upon vulcanization.
