  • 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 TPS of rubber antioxidants?
  • The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
  • Are rubber antioxidants a rational design?
  • The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
  • Are carbon dots a rubber antioxidant?
  • Carbon dots as rubber antioxidants The carbon materials, such as carbon black, graphene, fullerene, etc, are well known to be able to retard the aging processes of various polymers including polyolefine, rubber, polyamide, etc., due to the active trapping of radicals .
