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.
effect of thermo-oxidative aging on thermal elongation,antioxidant c with a smaller molecular weight (m w =358.5 g/mol) has more hydroxyl groups per unit mass (n c-oh =0.0056 n a) and the lowest steric hindrance compared with antioxidants a and d [39]. therefore, antioxidant c with better oxidation resistance has a greater influence on the thermal elongation results and lower elongation values.

- Which rubber antioxidants are used in China?
- Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
- 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.
- How can Antioxidants improve the antioxidative capacity of the rubber matrix?
- Generally speaking, as shown in Figs. 2 and 3, there are two main strategies to improve the antioxidant's antioxidative capability for the rubber matrix: (i) using two or more antioxidants together, and (ii) molecular design of antioxidants. Fig. 2.
- What are the future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
