production and use of typical rubber antioxidants
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.
environmental chemical rubber antioxidants,natural antioxidants are only found in nr, such as amino acids, tocotrienol, and betaines [], whereas physical and chemical antioxidants are widely used in various synthetic rubber products. the rubber-aging process comprises three stages: initiation, reaction, and termination [ 15 , 16 ], and the physical antioxidants are usually used to address the initiation stage of rubber aging.
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.

traditional rubber antioxidant rd(tmq) in nigeria widely used hot
china export quality rubber antioxidant tmq (rd) in tire rubber age resister , widely used for the production of tyre, rubber overshoes, sebific duct, adhesive tape, wire, cable and other rubber products. physical property proportion1.05. benzene , chloroform
recent progress in the rubber antioxidants price,this review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers. the oxidative degradation of rubber proceeds by a free-radical chain reaction mechanism [1]. as shown in fig. This product is combustible, when storing and transporting, always pay attention to fireproof and damp proof.

- 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 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.
- 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 .
- Why do we need antioxidants for rubber composites?
- Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
