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 accelerator polymer stabilizer / alfa chemistry,a vulcanization accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. vulcanization accelerator also decreases the amount of sulfur needed to cross-link the polydiene, which improves the aging properties
