  • What are the different types of rubber vulcanizing accelerators?
  • In rubber tire production, there are three commonly used rubber vulcanization accelerators that are similar in appearance (i.e., 2-mercaptobenzothiazole, 4,4′-dithiodimorpholine, and tetramethylthiuram monosulfide).
  • Which elastomers can be vulcanized?
  • Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur. As a result, several of the same accelerators that are used with sulfur vulcanization systems can be used with zinc oxide/neoprene systems. Because there are so many, accelerators are generally classified by chemical family.
  • 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.
  • 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.
