  • What is pentocure – ZMBT?
  • Pentocure – ZMBT is a semi-ultra fast accelerator for NR, SBR, NBR, BR and other diene rubbers. Pentocure – ZMBT critical cure temperature is approx. 120°C and dry rubber / latex based compounds are vulcanized quickly at 125°C.
  • Does ZMBT disperse in water?
  • Pentocure – ZMBT readily disperses in water in the presence of commonly used dispersing agents (e.g. sodium salt of polymerized alkyl naphthalene sulfonic acid) and is usually used as 50% dispersion in water for latex compounding applications.
  • 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 the difference between pentocure – ZMBT and MBT?
  • Pentocure – ZMBT critical cure temperature is approx. 120°C and dry rubber / latex based compounds are vulcanized quickly at 125°C. Pentocure – ZMBT is slightly lower than Pentocure – MBT; however, scorch safety is much higher and hence can be used in place of MBT for scorch control.
