  • 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 %.
  • How much air is released from a generic rubber manufacturing site?
  • Releases to air from a generic rubber manufacturing site have been estimated according to OECD emission scenario document to be 31 kg/day expressed as unreacted CBS. It is noted, that the major part of this amount is expected to be released in form of breakdown products.
  • 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.
