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.
