  • What is a thiuram accelerator?
  • The thiuram class comprises accelerators like TMTM, TMTD, TETD, TBzTD, and DPTT. Thiurams are highly efficient accelerators used in the vulcanization of NR, SBR, BR, NBR, and other highly unsaturated rubbers. They are particularly favored as primary accelerators for low-unsaturation rubbers like butyl (IIR) and EPDM, which undergo sulfur curing.
  • Which thiuram accelerator has the best cure rate?
  • The activity of various thiuram accelerators can be summarized as follows in terms of cure characteristics: Scorch Safety: TMTD exhibits the longest scorch safety, followed by TETD, and then TMTM. Cure Rate: TMTM, TETD, and TMTD all possess similar fast curing rates.
  • Can thiurams be used as a secondary accelerator?
  • They are particularly favored as primary accelerators for low-unsaturation rubbers like butyl (IIR) and EPDM, which undergo sulfur curing. In combination with thiazole/sulfenamide accelerators, thiurams are commonly used as secondary accelerators at levels of 0.05 – 0.4 phr.
  • What are thiazole accelerators?
  • Thiazole accelerators are activated by a combination of Zinc oxide and Stearic acid, resulting in a flat cure and vulcanizates with excellent resistance to reversion. The activity of thiazole accelerators can be summarized as follows: Scorch Safety: Thiazoles offer longer scorch safety compared to (MBT < MBTS < ZMBT).
