  • 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.
  • What is ZDMC accelerator?
  • ZDMC is an ultrafast accelerator of natural and synthetic rubber such as EPDM, SBR, NBR. Thiurams and thiazoles accelerator can delay the start of vulcanization and improve processing safety. Compared to ZDBC, ZDEC and ZEPC, ZDMC has a longer scorching time and shorter curing time, alkaline accelerator can activate it.
  • How is rubber vulcanized?
  • Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. The chemical reaction between sulfur and the Rubber Hydrocarbon occurs mainly at the C = C (double bonds) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator).
  • What is ZDBC used for?
  • Good storage stability. ZDBC is used as secondary ultra accelerator for thiazole and sulfenamide cure systems in general purpose polymers (NR, SBR, IIR, EPDM). It can be used as a primary accelerator in specialty applications as well as in latex. In latex applications ZDBC is mainly used in transparent goods and in prevulcanized latex.
