HENGDA-Si69C is a bifunctional polysulfide organosilane coupling agent that has been successfully used in the rubber and plastics industry. It is suitable for vulcanized rubber systems using silica, glass fiber, talc, mica, clay and other fillers as reinforcing agents. It can improve The reinforcing ability of fillers and increasing the wear resistance of rubber. It can be used as rubber additives - vulcanizing agents and activators. Applicable rubber types include NR, NBR, SBR, IR, BR, EPDM and their combined rubber compounds. During the vulcanization process, the cross-linking speed of the tetrasulfane group is basically the same as the sulfur reversion speed in sulfur vulcanization, which plays a role in resisting vulcanization reversion, thus improving the dynamic bending properties such as heat generation and crack elongation of the rubber. 4 S atoms It can also play a role in promoting vulcanization.
It can be used to make products under dynamic and static working conditions. Such as tires, rubber hoses, rubber rollers, tapes, cable insulation and coating materials, shoes and mechanical casting products, etc., can improve their wear resistance, cut resistance and pressure resistance; reduce hysteresis and water absorption; improve their mechanical properties, Adhesion performance; enhance its thermal aging performance, modulus and flex life.
