  • 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).
  • What is the role of accelerator in vulcanization?
  • Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates. Accelerators are also classified as Primary and / or Secondary accelerators based on the role they play in a given compound.
  • What is a vulcanization system?
  • A vulcanization system not requiring free or donated sulfur. (These are based on metal oxides, organic peroxides etc.) Para Benzoquinonedioxime and dibenzoyl quinine dioxime can cure many rubbers through their free radical reactions.
  • Which type of vulcanization system is used in SBR & BR?
  • In SBR & BR vulcanizates poly and di-sulfidic cross links are predominant. The conventional vulcanization system gives poor reversion; oxidative heat and long term flex resistance. However; the vulcanizates exhibit good tensile and tear strength, good fatigue and low temperature resistance.
