    Rubber and tire manufacturers rely on Cure-Rite Rubber Accelerators as a key part of the rubber vulcanization package. Cure-Rite accelerators control the rate of vulcanization, which can improve rubber manufacturing productivity and ensure the development of desirable properties―such as strength, elasticity, modulus, and oxidation stability―prior to curing.

  • 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 & 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
