  • 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.
  • Do recycled tire rubber products contain PPDS and TPS?
  • However, the occurrence of PPDs and TPs in recycled tire rubber products remains uncharacterized. Here, we analyzed tire wear particles (TWPs), recycled rubber doormats, and turf-field crumb rubbers for seven PPD antioxidants, five PPD-quinones (PPDQs), and five other 6PPD TPs using liquid chromatography-tandem mass spectrometry.
  • 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].
  • Does natural rubber have antidegradants?
  • Natural rubber already contains naturally occurring antioxidants that protect the polymer from oxidation. One of the key properties of antidegradants (antioxidants and /or antiozonants) is their solubility in the rubber matrix. The faster the rate of bloom, the less soluble the antidegradant is in the polymer system.
