  • 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.
  • 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 %.
  • What is a CBS granule?
  • CBS is a slight greyish powdery substance (vapour pressure 1.5 x 10-8 hPa at 20°C) which decomposes under the influence of heat. According to information provided by industry CBS is mainly used in dust suppressed forms (granulates or master batches).
  • 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 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.
