  • 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.
  • How many T vulcanisation accelerators are there in the world?
  • The world CBS production is estimated to 44,000 – 45,000 t for 1993. It is expected that the CBS demand will increase in the next years, because CBS in contrast to other vulcanisation accelerators cannot form toxic nitrosamine.
  • 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.
  • Is CBS a vulcanization agent?
  • CBS is subject to a rapid hydrolysis and it is emitted to the environment mainly in form of its degradation products from production and from its sole use as vulcanization agent. Therefore in this risk assessment also six environmentally relevant degradation products of CBS have been addressed.
