recent progress in the rubber antioxidants Rubber Auxiliary Agent,the most widespread used antioxidants are phenolic and amine-based synthetic antioxidants and 2,2,4-trimethyl-1,2-dihydroquinoline in rubber industry.
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).

the amine and phenolic antioxidants are the most widely used rubber antioxidants (fig. 1 b and c). generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
molecular dynamics investigation on the thermal-oxidative,the effect of molybdenum disulfide (2h-mos 2) on the properties of the composites of antioxidant 4020 and nitrile butadiene rubber (nbr) was investigated. two sets of composites, 4020/nbr and mos 2 /4020/nbr, were modeled using molecular dynamics simulations.

discover how rubber antioxidant 6ppd (4020) performs under high dynamic working conditions, extending the service life of rubber products such as tires and transmission belts. with excellent antioxidant and anti-ozone properties, 6ppd (4020) ensures reliability and durability in harsh environments.
rubber antioxidants and chemical 6ppd,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
overview of rubber antioxidant 6ppd (4020) 20mt price
this article discusses the application prospects of rubber antioxidant 6ppd (4020) in mechanical products, analyzes its anti-aging properties and advantages in improving product durability, and provides practical reference for industry practitioners.
recent progress in the rubber antioxidants Rubber Auxiliary Agent,currently, many commonly used rubber antioxidants are low molecular weight derivatives of aromatic amines and phenols, and they are plagued with volatility, migration, and extractability issues.
6ppd rubber antioxidant: characteristics, applications
6ppd (n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a highly effective rubber antioxidant with notable characteristics, including excellent heat resistance, anti-flex cracking properties, and compatibility with various rubber types.
synthesis and properties of a novel reactive and low,rubber composites containing antioxidants 4020 and 4010na were immersed and extracted, resulting in solutions that were noticeably darker in color than those of the rubber composites with gma-ppda antioxidants, which had also been immersed.
- 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 .
- 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 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.
- Are carbon dots a rubber antioxidant?
- Carbon dots as rubber antioxidants The carbon materials, such as carbon black, graphene, fullerene, etc, are well known to be able to retard the aging processes of various polymers including polyolefine, rubber, polyamide, etc., due to the active trapping of radicals .
