  • Which accelerators are suitable for natural rubber and synthetic 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. We offer a wide range of cure speeds from delayed action to ultra-accelerators.
  • 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 are accelerated elastomers?
  • from a large number of organic compounds. These contain nitrogen or sulfur, or both. They have been developed over a period of many years and the type and amount depends on the elastomer used, the predetermined processing requ ments, and the anticipated curing rates. Accelerators are ty
  • Which accelerator produces a Scorchy D modulus (crosslink density)?
  • d modulus (crosslink density) development. Secondary accelerators usuall produce scorchy, very fast curing stocks. Primary a celerators are sulfenamides and thiazoles.
