  • What is rubber accelerator CBS?
  • Rubber accelerator CBS (CAS No. 95-33-0) is a gray-white powder with a slight odor. It is an excellent accelerator for natural rubber, synthetic rubber, and latex. CBS accelerates the vulcanization process, which improves the mechanical properties, stability, and durability of rubber products.
  • 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 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.
  • 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.
  • 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 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.
