  • 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.
  • Which thiazole accelerator is used in dry compounding?
  • are aniline, carbon disulfide, and sulfur. The chief thiazole accelerators are 2-mercaptobenzothiazole (MBT), benzoth-iazole disulfide (MBTS), an the zinc salt of 2-mercaptobenzothiazole. The zinc salt is rarely used in dry compounding but is used more in latex foams and dipped goods. Both MBT and MBTS can cause scorching problems when used al
  • 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.
