    Vulcanization & Accelerators - Lusida Rubber Products

    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

    Mechanism of vulcanization promotion of rubber accelerator

    The vulcanization mechanism of rubber is still divergent. This is because in the production process of rubber products, the existence of insoluble natural rubber samples and a large number of simultaneous reactions have made it difficult for rubber molecules to become complex polymer networks, and the rubber vulcanization mechanism proposed in the early stage can be divided into two kinds

  • 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.
