Bis[3-(triethoxysilyl)propyl]disulfide is a chemical compound with the molecular formula (C₂H₅O)₃Si(CH₂)₃SSS(CH₂)₃Si(OC₂H₅)₃. This compound is commonly used as a coupling agent in various industrial applications, particularly in the rubber and plastic industries. Its role is similar to other silane coupling agents, facilitating adhesion and bonding between organic polymers (such as rubber or plastics) and inorganic surfaces (such as silica or metal oxides). This improves the mechanical strength, durability, and other properties of composite materials where it is used.

1.As an improved product of HENGDA-Si69, HENGDA-Si75 is a new bifunctional disulfide organosilane. Its specific sulfide distribution characteristics make it have better high temperature stability and avoid polysulfide silane desulfurization during high temperature mixing. Free sulfur is generated to vulcanize the rubber in advance.
2.HENGDA-Si75 can be uniformly dispersed in rubber, which improves the processing performance of rubber, and makes rubber products have excellent properties such as low heat generation and low wear resistance.
