  • What is PTDC & dixp vulcanisation accelerator?
  • PTDC and DIXP are recently developed ultra fast environmentally safer vulcanisation accelerators. They have major applications in dry rubber compounding (NR, SBR, NBR and EPDM) as primary or secondary accelerators, capable of replacing established thiurams or dithiocarbamates on a weight to weight basis and giving superior vulcanisate properties.
  • 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.
  • Why are accelerators used in vulcanizing elastomers?
  • Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. The selection of an accelerator will depend on the specific vulcanizing system and curing properties.
  • How effective is PTDC in a dry natural rubber?
  • In this context PTDC was evaluated for its effectiveness at 60, 80 and 100 ̊C in a dry natural rubber and compared with piperidinium cyclopentamethylene dithiocarbamate (PPD) and ZDBC-extra/ZIX and ZDEC. PPD and ZDBC-extra/ZIX are considered to be very effective in low temperature curing.
  • What is PTDC vulcanisation accelerator?
  • PTDC is a recently developed ultrafast environmentally safer vulcanisation accelerator based on a diprimary dithioamines and containing no metal ion and will comply with requirements of ‘end of vehicle life’.
  • Is dixp a good accelerator for carboxylated nitrile latex?
  • It is also an effective accelerator for carboxylated nitrile latex, when used in combination with NaMBT. The advantages pf this system are: Since DIXP does not contain nitrogen in its chemical structure, it cannot produce N-nitrosamines.
