- 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.
- Which antioxidants 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 ]. By contrast, phenolic antioxidants have less effect on rubber color, and thus are widely used in light-colored rubber products . 2.3. Heterocyclic Antioxidants ].
- Do Antioxidants improve the performance of rubber?
- Conclusions and Future Perspectives Antioxidants are widely used to improve the performance of rubber, and their production, especially 6PPD, is annually maintained at a high level .
- 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].
- 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 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 .
