  • What is sulfur vulcanization?
  • Vulcanization is the conversion of a high molecular material from the plastic to the elastic state. One of the key chemical reactions in this process is that of rubber with sulfur. Sulfur vulcanization, widely used in the rubber industry, requires the use of vulcanization accelerators such as Vulkacit®.
  • 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.
  • 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.
