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,rubber has a wide range of application prospects as an important material in the field of oil extraction and sealing rings. the effect of molybdenum disulfide (2h-mos2) on the properties of the composites of antioxidant 4020 and nitrile butadiene rubber (nbr) was investigated.
molecular dynamics investigation on the thermal-oxidative
the efect of molybdenum disulfide (2h-mos2) on the properties of the composites of antioxidant 4020 and nitrile butadiene rubber (nbr) was investigated. two sets of composites, 4020/nbr and mos2/4020/nbr, were modeled using molecular dynamics simulations.
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.

we further used the ageing coefficient (k) to comprehensively evaluate the anti-ageing performance of the elastomers (fig. 7 c), similar results were observed. i.e., the ccds can protect the nr composites more effectively compared to the widely used antioxidant 4020 in rubber industry.
rubber antioxidants and chemical 6ppd,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).
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,in this review, we summarized the recent advances in rubber antioxidants over the last 10 years and offered some perspectives to outline the challenges and future research directions for the rubber 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.
- 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.
- 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].
- Are rubber antioxidants toxic?
- Recent advances in the toxicity issue of rubber antioxidant With the increasing popularity of automobiles, tire wear particles, generated from tire material during use on roads, would ultimately enter the eco-system, such as soil, aquatic environment, etc .
