transformation products of tire rubber antioxidant 6ppd in,6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppdq), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation. to address these data gaps, gas-phase ozonation of 6ppd was.
- Are rubber antioxidants harmful to the environment?
- However, recent studies have revealed that their transformation products (TPs) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber antioxidants and their TPs.
- 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.
- How does a rubber matrix affect antioxidative performance?
- Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
- What are amine antioxidants in rubber?
- Amine antioxidant is the most common rubber antioxidant, which was produced as early as the 1970s and widely used in the rubber industry. Typical amine antioxidants include diaryl-secondary amine, acetone-amine condensation product, p -phenylenediamine, and aldehyde-amine condensation product antioxidants .
