  • What are vulcanization accelerators?
  • Vulcanization accelerator also decreases the amount of sulfur needed to cross-link the polydiene, which improves the aging properties of the vulcanized rubber. The vulcanization accelerators can be further classified as primary and secondary accelerators. Some representative examples of primary accelerators include thiazoles and sulfenamides.
  • Which Guanidines are used in vulcanization accelerators?
  • The only two guanidines that are used on a commercial scale in vulcanization accelerators are diphenyl guanidine (DPG) and N, N'-diorthotolyl guanidine (DOTG). Guanidines are not recommended for light colored goods because they cause a brown discoloration. Thiourea are ultrafast primary or secondary accelerators.
