rubber antioxidant 4020（6ppd） with high quality,6ppd is a polluting antioxidant. in addition to having good anti oxygen effect, it also has the functions of anti ozone, anti bending and cracking, and inhibiting harmful metals such as copper and manganese. cas no. 793-24-8. formula.
we first give a brief introduction of the oxidation process and oxidation mechanism for rubbers. then, we present the strategies to improve the anti-oxidative efficiency of rubber antioxidants. after that, recent advances to minimize the blooming and migration of antioxidants are summarized.
rubber antioxidants and their transformation products
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.
(pdf) rubber antioxidants and their transformation products,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.
rubber antioxidant 6ppd (4020) (high-class) with best quality
rubber antioxidant 6ppd (4020) (high-class) by henan rtenza is n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine grade. it offers antioxidant properties with excellent high temperature and flexing resistance to rubber compounds.
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).

it is an antiozonant and antioxidant for natural rubber and synthetic rubber, and has excellent protective effect against ozone cracking and flex fatigue. production method. a variety of methods can be used to prepare antioxidant 4020.
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 antioxidant 4020 6ppd for Tyres
Rubber antioxidant 4020. Chemical name: N-(1,3-dimethylbutyl)-N-phenyl-p-phenylenediamine. Molecular formula: C18H24N2. Molecular weight: 268.4. It can soften sizing material, so can be used for tires and other kinds of rubber products, also can be used as heat oxygen stabilizer for polyethylene, polypropylene and acrylic resin.
Rubber Antioxidant 6PPD technical data sheet,technical data sheet (tds) chemical name: n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine. other name: 4020. molecular formula: c18h24n2.
- 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.
- Do Antioxidants improve the performance of rubber?
- Conclusions and Future Perspectives Antioxidants are widely used to improve the performance of rubber, and their production, especially 6PPD, is annually maintained at a high level .
- Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
- 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) [7, 8].
- 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.
