A bifunctional polysulfide organic silane coupling agent that has been successfully used in the rubber and plastic industry.
Suitable for vulcanized rubber systems with fillers such as white carbon black, glass fiber, talc powder, mica, clay, etc. as reinforcing agents, it can improve the reinforcing ability of fillers and increase rubber wear resistance.
As rubber additives - vulcanizing agents, activators, suitable types of rubber include NR, NBR, SBR, IR, BR, EPDM, and their blends. During the vulcanization process, the cross-linking speed of the polysulfide groups in 669 is basically the same as the sulfur reversion speed in sulfur vulcanization, which plays a role in resisting vulcanization reversion and improving the dynamic bending properties of rubber such as heat generation and crack extension. The multi S atoms can also play a role in promoting vulcanization.
It can be used to produce products under dynamic and static working conditions, such as tires, rubber hoses, rubber rollers, tape, cable insulation and wrapping materials, shoes, and mechanical casting products, which can improve their wear resistance, cutting resistance, and pressure resistance; Reduce hysteresis and water absorption; Improve its mechanical and adhesive properties; Enhance its thermal aging performance, modulus, and flexural life.
Adding sulfur-containing silane coupling agents to the rubber tire industry can not only reduce the risk of tire blowouts caused by high temperatures during high-speed or long-term driving, but also reduce the rolling resistance of tires on the road, thereby reducing gasoline consumption and CO2 emissions, achieving the environmental protection concept of energy conservation and carbon reduction.
