  • What is accelerator BZ (ZDBC)?
  • Accelerator BZ (ZDBC) is a very active non-discoloring, non-staining accelerator for EPDM (non-blooming dosage in EPDM is up to 2.0 phr while other dithiocarbamates are limited to 0.8 phr maximum before bloom occurs), as well as NR and SBR latexes.
  • 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 vulcanizing agent?
  • Vulcanizing agent is the most important ingredient in this system as it is used to strengthen the rubber compound properties through the vulcanization process. Normally, this process is conducted by heating the mixture of raw rubber with vulcanizing agents at specific vulcanization time in a pressurized mold.
  • What is vulcanization of rubber?
  • Vulcanization involves chemical procedure wherein rubber is blended with activators, accelerator, and Sulfur at the temperature of 140–160 °C (Fig. 4.6). Cross-linking occurs among long molecules of rubber, to add up the tensile strength, tenderness, and resilience toward weather . Fig. 4.6. Vulcanization of synthetic rubber .
