  • How vulcanization accelerator is used in rubber goods manufacture?
  • CBS is exclusively used as vulcanization accelerator in rubber goods manufacture. Vulcanization transforms the rubber from the thermoplastic into the elastomeric state at temperatures between 150 and 200 °C. CBS is loaded to the rubber in concentrations of 0.5– 1% (ww) but it breaks down during the curing process.
  • Is CBS a rubber accelerator?
  • Almost all rubber compounds on the market contain rubber accelerator as CBS in a wide range of products, but it is difficult to know which rubber product contain which rubber accelerants. Therefore the use of CBS in consumer product cannot be ruled out completely.
  • Does CBS affect the processing of rubber goods?
  • Due to the resulting low concentration of CBS, a considerable exposure to CBS during the processing of rubber goods is not expected. Therefore, the processing of rubber, e.g. cutting, melting, is not considered in this report. Occupational exposure limits for CBS have not been established in Western Europe and USA.
  • 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.
