  • Which accelerator is most commonly used in rubber industry?
  • most commonly used by the Rubber Industry.There is a wide variety o accelerators available to the compounder. For ease in understanding, it is useful to c assify accelerators by chemical structure. One such classifi ation, made by the ASTM s as follows: 1 Thiazoles (Me capto), 2. Sulfenami es, 3. Guani ines, 4. Dithiocarbamat
  • Are primary and secondary accelerators a problem in nitrile latex applications?
  • Primary accelerators are relatively slow and have a delayed onset of cure. Secondary accelerators activate primary accelerators and increase speed of vulcanisation but they are well known contact sensitizers (Type IV allergy) and can pose serious health implications, and therefore can be major problem in nitrile latex applications like gloves.
  • Can ZDBC be substituted with a safer secondary accelerator?
  • This aimed to substitute ZDBC with a safer secondary accelerator. ZnO was used as an activator for sulphur vulcanisation to improve cross-link efficiency. However, a cure system with ZnO alone takes three times longer to cure latex compared to an accelerated system.
  • Are secondary accelerators safe in nitrile latex glove formulation?
  • These accelerators are nitrosamine safer compared to more traditional accelerators like zinc diethyldithiocarbamate (ZDEC) and zinc dibutyldithiocarbamate (ZDBC). Our work investigated the contribution of these secondary accelerators in nitrile latex glove formulation from a rheological point of view and mechanical testing of dipped films.
