  • What is accelerator in rubber vulcanization?
  • An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates.
  • 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.
  • What causes vulcanization of rubber compound?
  • Sometimes the rubber processing temperatures reach a temperature just 10°C below the actual vulcanization temperature and this induces 'onset' which is known as Scorch or Premature Vulcanization. The 'scorch' at a little advanced stage renders rubber compound useless for further processing or vulcanisation.
  • Which vulcanizing agent is best for olefin rubber?
  • The vulcanizates exhibit good tensile and compression set resistance properties and heat aging resistance. Phenol formaldehyde resins with para-alkyl substitutes can be used as vulcanizing agents for olefin rubbers (both high and low unsaturation rubbers).
