  • 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.
  • Can CBS be used as a vulcanisation accelerator?
  • Use of CBS as a vulcanisation accelerator in the rubber industry (e.g. rubber goods, tires) During the vulcanisation (curing) process, CBS like any other vulcanising agent is reacting for at least 95 %.
  • Does rubber industry emit vulcanisation agents?
  • In rubber industry, no releases of vulcanisation agents to the surface waters occur. Consequently, no risks for aquatic environment are expected. This conclusion covers also the exposure of soil for the CBS production and rubber industry (emissions to air). Conclusion (i on hold) There is a need for further information and/or testing.
  • How much CBS can be retained in a rubber product?
  • Taking into account that the maximum concentration of CBS in the uncured compounds is 3.5 % (technical rubber), the amount of CBS that can be retained in the finished product is limited to 0.2 %. Due to the resulting low concentration of CBS, a considerable exposure to CBS during the processing of rubber goods is not expected.
