  • How tbztd is used in vulcanization system?
  • An efficient vulcanization system has been selected to get heat and reversion resistance to the natural rubber vulcanisates during the long service life in engineering applications. Safe natural rubber vulcanisates have been prepared using TBzTD in an efficient vulcanisation system.
  • Can tbztd replace TMTD in natural rubber vulcanisates?
  • The study establishes that in natural rubber vulcanisates it is possible to develop equivalent and even superior crosslink densities and the mechanical properties by replacing TMTD which is known to be carcinogenic with marginally high dosage of TBzTD which is non-regulated and safe. IV.
  • What is vulcanisation & curing?
  • Vulcanisation or curing is the insertion of a relatively small number of chemical cross links, by the addition of vulcanizing agents along the polymer chains to enable the strength and elastic properties inherent in raw rubber to be fully realized . This is achieved when the compounded rubber is heated to an appropriate temperature.
  • Are tetra methyl thiuram disulphide vulcanised rubber articles carcinogenic?
  • The rubber articles that are vulcanised using conventional accelerators such as tetra methyl thiuram disulphide (TMTD) are carcinogenic because of the production of nitrosamines (NA) during heating for the vulcanisation reaction. The nitrosamine producing TMTD has to be replaced with a safe accelerator.
