  • How MBTs/DPG & CBS/DPG accelerator systems perform in natural rubber compound?
  • Performance of MBTS/DPG and CBS/DPG accelerator systems in natural rubber compound are evaluated through assessing the Mooney viscosity, curing characteristics and flow property at a fixed angle.
  • Which accelerator is used on natural rubber (NR) compound?
  • Accelerators, such as 2,2'-Dithiobis (benzothiazole) (MBTS), N-Cyclohexylbenzothiazole-2-Sulfenamide (CBS) and diphenyl guanidine (DPG), has been selected for the study. Response of paired accelerator, MBTS/DPG and CBS/DPG in various ratio, on natural rubber (NR) compound was evaluated.
  • How sulfenamide is converted into MBTs?
  • Once formed, MBT is immediately converted to MBTS according to reaction 2 (Figure 8). Thus, the key reactions of sulfenamide (CBS) accelerator in induction period are the thermal decomposition of CBS into MBT and the reaction of remaining CBS with MBT to form MBTS (Anandhan et al., 2012).
  • How is MBT converted to MBTs?
  • MBT is initially generated during thermal decomposition of CBS as expressed on reaction 1 (Figure 7). Once formed, MBT is immediately converted to MBTS according to reaction 2 (Figure 8).
  • Does adding MBTs increase flow rate?
  • The addition 0.2 phr of DPG has markedly increased the rate in MBTS-based, and it gives the lowest rate among the accelerator sets. Further, it has been observed that addition of MBTS reduces the flow rate. In CBS-based, the rate is increased upon the addition of DPG. Further addition of CBS tends to increase it.
