rubber aging agent 6ppd(4020) national standard quality,rubber antioxidant 4020/6ppd. chemical name:n- (1,3-dimethyl-buty)-n’-phenyl-p-phenylenediamine. molecular:c18h24n2. cas no.: 793-24-8. molecular weight: 268.40. hs code: .
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.
rubber antioxidant 6PPD price antioxidant 4020
recently, roadway releases of n,n′-substituted p-phenylenediamine (ppd) antioxidants and their transformation products (tps) received significant attention due to the highly toxic 6ppd-quinone. however, the occurrence of ppds and tps in recycled tire rubber products remains uncharacterized.
antioxidant sustained release from carbon nanotubes for,Rubber Antioxidant 6PPD is puce solid granule benzene, acetone and etc.Insoluble in water; Will become black on exposure to air, but cause no effect on its properties.Due to low melting point, it should be stored away from high temperature.
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.
rubber antioxidants and their transformation products,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).

for example, α-tocopherol was revealed as a natural additive in polymer materials. 19,20 it was used as a radical scavenger in low density polyethylene, and was shown to be more efficient than the commercial antioxidants irganox 1010 and 1076. 21 in addition, the results demonstrated that the incorporation of phosphite-type secondary antioxidant...
rubber antioxidants and chemical 6ppd,in this review, we first summarize the category and application of rubber antioxidants in the world, and then demonstrate the formation mechanism of their tps in the environment, emphasizing their influence on the ozone oxidative degradation.
rubber antioxidant 6ppd (4020) a must-have for improving
rubber antioxidant 6ppd (4020) is a highly efficient multi-purpose antioxidant with excellent antioxidant and high temperature resistance properties. it can significantly improve the durability and protective effect of rubber products, and is especially suitable for complex and harsh dynamic working conditions. .
the use of crude carbon dots as novel antioxidants for,in contrast, the nr containing antioxidant 4020 or ccds exhibit substantially improved anti-aging performances. and the anti-oxidative efficiency of ccds is even superior than for commercial antioxidant 4020.
- 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 4020 slow down rubber chain oxidation?
- Indicating that both the antioxidant 4020 and CCDs could slow down the rubber chain oxidation. Also, it seems that the change ratio for NR/CCDs composites is lower than for NR/4020 composites, suggesting that the anti-oxidative ability of CCDs is superior compared to antioxidant 4020.
- Do antioxidants and their TPS increase environmental risk awareness of rubber products?
- To our knowledge, this is the first review on antioxidants and their TPs in the environment, which may elevate the environmental risk awareness of rubber products and their TPs in the near future.
- 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.
