rubber antioxidants and their transformation products mdpi,antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. 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
- What are rubber antioxidants?
- Rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . To date, the annual global consumption of rubber antioxidants is over 700,000 tons, accounting for about 40% of the total amount of rubber additives.
- Does antioxidant 2246 protect rubber from aging?
- Among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. Because hydrogen in phenolic antioxidants can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21, 22].
- Are uracil derivatives antioxidants for natural rubber?
- New uracil derivatives as antioxidants for natural rubber. Pigment Resin Technol. 2007;36:224–234. doi: 10.1108/03699420710761825. [CrossRef] [Google Scholar] 26. Hu D.C., Jia Z.X., Zhong B.C., Chen Y.J., Luo Y.F.
- 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].
