  • vulcanization accelerators

    Vulcanization Accelerators

    An accelerator is defined as a compound that increases the speed of vulcanization and that enables vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also decreases the amount of sulfur needed to cross-link the polydiene, which improves the aging properties of the vulcanized rubber.

    The function of rubber vulcanization accelerator

    Before people do not realize the organic accelerator, rubber vulcanization accelerator is mainly used alone sulfur or a sulfur and inorganic accelerator.However, this process requires a lot of sulfur, and high curing temperature, as well as quite a long curing time, and the considerable risk of excessive sulfur.

  • vulcanization & accelerators

    Vulcanization & Accelerators

    Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. The chemical reaction between sulfur and the Rubber Hydrocarbon occurs mainly aC (doublet the C = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C
