  • What type of accelerator is used in vulcanization?
  • Primary accelerator: this group of accelerators usually have a long burning time and are quickly cooked in the main stage of vulcanization Polymer accelerators are used to produce various types of rubber such as isoprene, styrene, butadiene and NBR. Sulfonamides are one of the most popular primary accelerators.
  • How do antidegradants protect vulcanizates from aging?
  • Ozone or dynamic stress (fatigue) lead to cracking on the surface of the rubber article. Antidegradants such as Vulkanox® are chemicals which protect the vulcanizates against damaging external influ-ences. Depending on the chemical structure, they act against one or more of the aging processes mentioned.
