  • What is the difference between antioxidants 4020 and 4010na?
  • Rubber composites containing antioxidants 4020 and 4010NA were immersed and extracted, resulting in solutions that were noticeably darker in color than those of the rubber composites with GMA-PPDA antioxidants, which had also been immersed.
  • Why do we need antioxidants for rubber composites?
  • Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
  • Do antioxidants and their TPS increase environmental risk awareness of rubber products?
  • To our knowledge, this is the first review on antioxidants and their TPs in the environment, which may elevate the environmental risk awareness of rubber products and their TPs in the near future.
  • 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.
