Physical and chemical data

Product application and characteristics

It is a bifunctional polysulfide organosilane coupling agent successfully used in rubber and plastics industry.

It is suitable for vulcanized rubber system with carbon black, glass fiber, talc powder, mica, clay and other fillers as reinforcing agents, which can improve the reinforcing ability of fillers and increase the wear resistance of rubber. As rubber additives - vulcanizing agent, active agent, applicable rubber types include NR, NBR, SBR, IR, BR, EPDM and their combined rubber. In the vulcanization process, the crosslinking rate of the tetrathionyl group is basically the same as the sulfur return rate in sulfur vulcanization, which plays the role of anti-vulcanization return, thereby improving the dynamic bending properties of rubber such as heating property and crack elongation, and the 4 S atoms can also play the role of vulcanization promotion. It can be used to make products under dynamic and static working conditions, such as tires, rubber hoses, rollers, tapes, cable insulation and coating materials, shoes and mechanical casting products, etc., which can improve their wear resistance, cut resistance and pressure resistance; Reduce hysteresis and water absorption; Improve its mechanical properties, bonding properties; Enhance its thermal aging performance, modulus and flexural life. Recommended usage :1.0-4.0 PHR.
