  • What is accelerator in rubber vulcanization?
  • An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates.
  • Why are dithiocarbamates used in vulcanization of rubber and latex?
  • Zinc salts of various dithiocarbamates are widely used as accelerators in vulcanization of dry natural rubber and latex because of the excellent properties of the vulcanizates produced. Unfortunately, dithio- carbamates, being secondary amines, produce harm- ful ^-nitrosamines.
  • How many accelerators are used in rubber vulcanizates?
  • r temperature and with greater efficiency. Over 150 different chemicals belonging to different classes of composition are known to function as acceler-ators for rubber vulcanizates of which around 50 accelerators are most commonly used by the Rubber Industry.There is a wide variety o
  • Which accelerators are used in vulcanization of NR latex films?
  • Comparison of crosslink efficiencies of the accelerators ZDEC, ZMBT, DPG and ZMBT/DPG in vulcanization of NR latex films. 2.5/ig/kg for the volatile JV-nitrosamines and the nitrosatable compounds, respectively.
