  • Are guanidines a good choice for thick walled rubber products?
  • Guanidines are good choice for thick walled rubber products. The vulcanization in the presence of guanindes has relatively high crosslink density and good physical-mechanical properties; they are less resistant to thermo-oxidative ageing, because polysulfide cross-links dominate in their network.
  • What are guanidines used for?
  • Guanidines are slow accelerators with short induction period and broad vulcanization plateau and require the use of zinc oxide for activation. They have alkaline character. They are suitable also into compounds containing additives of strongly acidic character and into compounds filled with SiO2.
  • What is n n diphenylguanidine (DPG)?
  • N,N’-Diphenylguanidine (DPG) is a vulcanization accelerator for natural and synthetic rubbers. Furthermore, N,N’-Diphenylguanidine (DPG) a secondary accelerator, activating Thiazoles (MBT, MBTS), Thiurams (TMTM, TMTD) or Sulfenamide (CBTS) in NR (0.1-0.5phr), SBR (0.15 – 0.75phr) and NBR (0.1-0,5phr) applications.
