  • What is a dithiocarbamate accelerator?
  • Dithiocarbamate accelerators are extensively used as ultra-fast accelerators in NR latex-based compounds. They also find applications as primary or secondary accelerators in most dry rubber-based sulfur-cured compounds. Activation of dithiocarbamate accelerators requires Zinc oxide and Stearic acid, resulting in rapid vulcanization.
  • What types of rubber accelerators do you offer?
  • We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber. We offer a wide range of cure speeds from delayed action to ultra-accelerators. Below is a rubber accelerators list of products that we offer.
  • Do dithiocarbamates vulcanize quickly?
  • Dithiocarbamates exhibit very low scorch safety, faster cure rates, and higher crosslink density. This enables rubber products to be vulcanized quickly at relatively low temperatures (115 – 120°C). However, compounds accelerated with dithiocarbamates have a narrow plateau, which means over-cure and reversion can occur rapidly.
  • What are thiazole accelerators?
  • Thiazole accelerators are activated by a combination of Zinc oxide and Stearic acid, resulting in a flat cure and vulcanizates with excellent resistance to reversion. The activity of thiazole accelerators can be summarized as follows: Scorch Safety: Thiazoles offer longer scorch safety compared to (MBT < MBTS < ZMBT).
