  • 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 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.
  • Does mercapto decelerate vulcanization?
  • mercapto or sulphonamide accelerators decelerates the vulcanization process. Scorch and vulcanization times are reduced. The degree of crosslinking is not greatly affected. Basic accelerators such as aldehydeamine and guanidine have thiazoles and as a sulphur-free vulcanizing agent.
  • How does a thiuram disulfide vulcanize?
  • Part or all of the sulfur may be replaced by an accelerator that is also a sulfur donor such as a thiuram disulfide. 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.
