  • How to increase the speed of vulcanization of rubber?
  • Chemindustries offers 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 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.
  • Which accelerators are suitable for natural rubber and synthetic 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. We offer a wide range of cure speeds from delayed action to ultra-accelerators.
  • What determines vulcanization rate?
  • The accelerator determines the rate of vulcanization, whereas the accelerator to sulfur ratio dictates the efficiency of vulcanization and, in turn, the thermal stability of the resulting vulcanizate. Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur.
