  • 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 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.
  • 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.
  • 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.
