    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

  • 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.

    Vulcanization - an overview | ScienceDirect Topics

    Vulcanization. Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.

    Charles Goodyear and the Vulcanization of Rubber

    It would take Goodyear several more years to recreate the chemical formula and perfect the process of mixing sulfur and rubber at a high temperature; he patented the process in 1844, the year after establishing the Naugatuck India-Rubber Company in Naugatuck. Goodyear named his discovery vulcanization, after Vulcan, the Roman god of fire.
