  • Which rubber accelerators are suitable for vulcanization?
  • Western Reserve Chemical offers a full range of rubber accelerators to increase the speed of the vulcanization of rubber. 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.
  • What is accelerator TmTm?
  • Accelerator TMTM provides very good processing safety while still allowing for high cure activity. Unlike the thiuram disulfides, the monosulfide TMTM will not produce cures in the absence of added elemental sulfur. Accelerator TMTM is also available as Akroform® TMTM-80. This polymeric masterbatch contains 80% Accelerator TMTM.
  • 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).
  • 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.
