  • Which rubber antioxidants are used in China?
  • Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
  • What are the different types of antioxidants in rubber?
  • Chemical antioxidants are generally classified as amine, phenolic, heterocyclic, phosphite, and nickel salts (nickel dibutyl dithiocarbamate (NBC)) antioxidants according to their chemical structure (Figure 1). During the rubber production, various antioxidants are often used as a mixture to improve performance and ensure an antiaging effect.
  • Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
  • Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
  • Is MBZ 445 a good antioxidant for EPDM?
  • In the thermal-aging testing, the retention of elongation at break for the rubber sample with combined antioxidants (MBZ:445=2:1) is superior to that of other samples (Fig. 2 c), demonstrating the synergistic antioxidative effects between MBZ and 445 for EPDM.
