  • What vulcanizing agent is used in rubber?
  • Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
  • 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.
  • Which accelerator is used for vulcanization?
  • The basic accelerators such as Guanidines, Thiurams, and Dithiocarbamates etc are used as Secondary accelerators to activate the primary accelerators. The use of secondary accelerators increases the speed of vulcanization substantially but at the expense of scorch safety.
  • 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.
