In tire manufacturing, the bonding strength between rubber and inorganic fillers (such as silica and carbon black) is crucial in determining performance. IOTA Si69 (bis-[3-(triethoxysilyl)propyl]-tetrasulfide) is a coupling agent that enables this bonding. It not only improves the interfacial bonding between rubber and fillers but also participates in the cross-linking reaction during vulcanization, thus significantly enhancing the overall performance of the tire.

Adding IOTA Si69 to systems containing natural rubber, styrene-butadiene rubber, and butadiene rubber can effectively improve tensile strength, tensile strength at a given elongation, and tear resistance, while reducing compression set. Its vulcanization reaction is mild and stable, reducing the risk of scorching and extending processing time.

More importantly, IOTA Si69 reduces heat generation during tire operation, resulting in lower tread temperature rise and improved wear resistance and rolling resistance. This means lower energy consumption and better grip when vehicles are operating at high speeds.

With its excellent reinforcing and fatigue-resistant properties, IOTA Si69 has become an indispensable additive in green tire production. Whether it's heavy-duty truck tires, passenger car tires, or off-road tires, IOTA Si69 silently protects every safe journey.
