  • Which rubber accelerators are suitable for vulcanization?
  • Western Reserve Chemical offers a full range of rubber accelerators to increase the speed of the vulcanization of rubber. We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber.
  • 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.
  • What vulcanizing agent is used in rubber?
  • Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
  • What types of rubber accelerators do you offer?
  • We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber. We offer a wide range of cure speeds from delayed action to ultra-accelerators. Below is a rubber accelerators list of products that we offer.
  • What is Accelerated vulcanization of rubber?
  • The chemistry of the accelerated vulcanization of BR, SBR, and EPDM appears to have much in common with the vulcanization of natural rubber: Before the formation of crosslinks, the rubber is first sulfurated by accelerator-derived polysulfides (Ac-S~-Ac) to give macromolecular, polysul- fidic intermediates (rubber-Sx-Ac).
  • Why are accelerators used in vulcanizing elastomers?
  • Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. The selection of an accelerator will depend on the specific vulcanizing system and curing properties.
