Fórmula estructural:
Características: Si-69 es un organosilano que contiene azufre que contiene grupos bifuncionales. Se puede usar en la combinación de caucho y material base blanco que contiene grupos silanol.
Especificaciones:

Application: It is suitable for vulcanized rubber systems with fillers such as white carbon black, glass fiber, talc, mica, clay and other fillers, which can improve the reinforcement ability of the filler and increase the wear resistance of rubber. As rubber additives-vulcanizing agent, active agent, suitable rubber types include NR, NBR, SBR, IR, BR, EPDM, etc. and their combined rubber materials. During the vulcanization process, the cross-linking speed of the tetrasulfanyl group is basically the same as the sulfur reversion rate in sulfur vulcanization, which plays a role in resisting vulcanization reversion, thereby improving the dynamic bending properties of rubber such as heat generation and crack elongation. 4 S atoms can also play a role in promoting vulcanization. It can also be used to make products under dynamic and static working conditions, such as tires, hoses, rubber rollers, tapes, cable insulation and covering materials, shoes and mechanical casting products, which can improve their wear resistance, cut resistance and pressure resistance; Reduce hysteresis and water absorption; improve its mechanical properties and bonding properties; enhance its thermal aging properties, modulus and flex life.
