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.

The latest development of rubber antioxidants
50 fillers in rubber systems such as silica, also exhibit a synergistic effect with antioxidants to enhance the antioxidative ability. 51 md simulations can also explain the diffusion and action.
nurvinox ble rubber antioxidant nurchem,cas no.: 68412-48-6. rubber antioxidant ble is a kind of commonly used rubber antioxidant. it has good resistance to heat、oxygen、bending,fatigue ageing, and can replace phenyl-α-naphthylamine、phenyl-β-naphthylamine. it is mainly used for natural ,polychloroprene butadiene,butylcyanide . butylbenzene and other synthetic rubbers, and used.
an alternative antioxidant for sulfur-vulcanized natural
in this work, a novel chitosan‐based macromolecular rubber antioxidant (denoted as cos‐ao) was successfully synthesized by using chitosan (cos) and 3‐(3,5‐di‐tert‐butyl4.
rubber antioxidants and their transformation products,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.
- 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.
- 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].
- What are the TPS of rubber antioxidants?
- The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
- Are rubber antioxidants toxic?
- (2) The toxic effects of rubber antioxidants and their TPs may be evaluated via computational toxicology combined with traditional toxicological methods, including studies of short-term and sub-lethal exposure effects, the potential for mortality, mechanism of effect, and interaction with environmental variables.
