  • 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.
  • 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.
  • What are the main products of rubber industry?
  • The most important products of rubber industry are automobile tires which take about 2/3 of the total rubber production. The remaining rubber is used for various types of “rubber goods”. Of these rubber goods, 65 % of the volume is used in the automotive branch.
  • How much peclocalair does a rubber manufacturing site emit?
  • For a generic rubber manufacturing site, PEClocalair of 8.62 μg /m3 as CBS -equivalent has been estimated according to the OECD emission scenario document. It is noted, that the majority of this amount is expected to be present as degradation products.
