  • What are the characteristics of DPG rubber?
  • 2. Characteristics of DPG: - Acceleration: DPG functions as a medium-fast primary accelerator, meaning it promotes the vulcanization process in rubber production. - Moderate reactivity: It offers a balanced level of reactivity, making it suitable for a wide range of rubber types, including natural rubber (NR), synthetic rubber, and blends.
  • What is accelerator DPG?
  • Accelerator DPG is useful as an accelerator/activator for natural rubber, SBR and NBR. It activates accelerators such as MBT, MBTS and sulfenamides. It is a strong secondary for CBTS, BBTS, OBTS, MBT and MBTS. DPG requires the use of zinc oxide and fatty acids. DPG provides satisfactory processing safety and storage stability to rubber compounds.
  • Does DPG increase aging resistance of rubber?
  • Moreover, Ahsan et al. reported that DPG used to activate other accelerators imparted the high aging resistance of rubbers. ... ... Natural rubber (NR) compounds can be cross-linked by sulfur (vulcanization), peroxides (cure), or sulfur donor accelerators, such as tetramethylthiuram (TMTD).
  • What are the advantages of DPG?
  • Moderate reactivity: It offers a balanced level of reactivity, making it suitable for a wide range of rubber types, including natural rubber (NR), synthetic rubber, and blends. - Good scorch safety: DPG provides good scorch safety, preventing premature curing during processing and allowing for extended processing time.
  • Is DPG a good accelerator for aging elastomers?
  • The better resistance on the thermo-oxidative aging of elastomers cured with DPG as compared to other accelerators was reported by Travas-Sejdic et al. for NR vulcanizates. Moreover, Ahsan et al. reported that DPG used to activate other accelerators imparted the high aging resistance of rubbers. ... ...
  • What happens if DPG is present in a rubber compound?
  • ity of the rubber when there is DPG in the compound.When the DPG is present, there is an overall low r silica filler flocculation in the rubber compound. Looking at the viscosity of the rubber before vulcaniza-tion takes place, you can see that the DPG compounds have a lo er viscosity than the compound with no DPG (Fig. 6). This i
