With the upgrading of EU tire labeling regulations and the increasing demand for low rolling resistance tires from new energy vehicles, sulfur-containing silane coupling agents have become an indispensable key additive in green tire formulations. Anhui Aiyota's bis-[3-(triethoxysilane)-propyl]tetrasulfide (corresponding to Si69 type) and disulfide (corresponding to Si75 type) products are helping tire companies achieve breakthroughs in both performance and environmental protection.

The sulfur atoms in the sulfur-containing silane molecules can undergo cross-linking reactions with the rubber molecular chains during vulcanization. Simultaneously, the ethoxysilane groups form chemical bonds with the hydroxyl groups on the surface of silica, effectively solving the problem of silica dispersion in the rubber matrix. Actual test data shows that adding 5-8 parts of sulfur-containing silane reduces tread rolling resistance by 20-30%, improves wet skid performance by 15%, and improves wear resistance by 25%, perfectly balancing the performance contradictions of the "devil's triangle."

Aiyota's sulfur-containing silane series offers two specifications: liquid concentrate and 50% carbon black pre-dispersed masterbatch. The pre-dispersed products avoid dust pollution, improve metering accuracy, and shorten mixing time. The sulfur content of our products is precisely controllable; tetrasulfides are suitable for high-performance tires, while disulfides offer superior processing safety. Our company has obtained IATF 16949 quality system certification and provides stable supply to several leading tire manufacturers. Our technical support team can provide formula optimization and process adjustment services.
