ippd antioxidant 4010na|n-isopropyl-n`-phenylenediamine,application: antioxidant ippd is a kind of polluting anti-oxidation agent in various rubbers. it has good performance for oxygen and ozone resistance, flexible and crack resistance, cracks by sunlight and inhibition of harmful metal ions like copper and manganese.
N-Isopropyl-N'-phenyl-p-phenylenediamine (often abbreviated ippd) is an organic compound commonly used as an antiozonant in rubbers. like other p-phenylenediamine -based antiozonants it works by virtue of its low ionization energy, which allows it to react with ozone faster than ozone will react with rubber. [2]
the effect of antioxidant concentration of n-isopropyl-n
the purpose of this study is to compare the effect of anti-oxidants types ippd and tmq and mixing time of vulcanization of the physical properties, mechanical properties, microstructure and elemental composition of the synthesis of natural rubber compound.
advantages of rubber antioxidant ippd in tropical regions,explore the benefits of rubber antioxidant ippd in enhancing the durability and market competitiveness of rubber products in tropical climates. learn how ippd can extend the service life of rubber and improve product resistance to aging.
rubber antioxidant ippd(4010na) rubber accelerator
ippd (4010na) rubber antioxidant, a high activity antioxidant for matural and synthetic rubber provides powerful antiozonant and antioxidant properties with excellent high temperature.
a nation-wide study for the occurrence of ppd antioxidants,three kinds of antioxidants 6ppd, dnpd and dppd were the dominant ppds in sampled road dusts. as ozonation product of 6ppd, 6ppd-q had the highest proportion in most road dusts. the concentration and composition of σppds and 6ppd-q varied largely from city to city.
influence of different types of antioxidants on the aging
influence of period of thermo-oxidative aging at 80 ℃ on the storage modulus g′ as a function of amplitude for nr vulcanizates with 60 phr carbon black and by using of different kinds of antioxidants: ippd (a), 6ppd (b) and tmq (c).

It is commonly used in tire manufacturing and can significantly improve the aging resistance and overall performance of rubber, helping to improve durability and safety.
comparative analysis of rubber antioxidant ippd and other
explore the comparative analysis of rubber antioxidant ippd (n-isopropyl-n'-phenyl-p-phenylenediamine) with other antioxidants in this comprehensive review. learn about the anti-aging advantages, diverse application fields, and cost-effectiveness of ippd in the rubber manufacturing industry.
rubber antioxidants and their transformation products,by contrast, chemical antioxidants are usually used to address the reaction stage of rubber aging. according to the different fracture modes of the molecular chain of raw rubber materials, different chemical antioxidants are added to block the growth reaction chain during aging [15].
- Are 6PPD and IPPD a contaminant?
- 6PPD and IPPD were detected in white shrimp samples collected from aquafarms. Given the high toxicity of N- (1,3-dimethylbutyl)-N’-phenyl- p -phenylenediamine (6PPD) derivatives, such as 6PPD quinone (6PPDQ) to salmon, as well as their ubiquitous presence in the environment, the contaminant of aquatic food products has drawn significant attention.
- How does ozone affect IPPD?
- IPPD is prone to process called blooming, where it migrates to the surface of the rubber. This can be beneficial to the tire, as ozone attacks the tire surface and blooming therefore moves the antiozonant to where it is most needed, however this also increases the leaching of IPPD into the environment.
- Does NaOH improve the recovery of 6PPD and 4-adpa?
- Particularly, the recovery of 6PPD and 4-ADPA is much improved by the addition of NaOH. Under alkaline conditions, the molecular form of 6PPD is not easy to be excited as (*6PPD), so it is relatively stable .
- Why is 6PPD stable under alkaline conditions?
- Under alkaline conditions, the molecular form of 6PPD is not easy to be excited as (*6PPD), so it is relatively stable . Moreover, the lower oxidation potential of free radicals under alkaline conditions may reduce the oxidative degradation of diphenylamine . These may account for the increased recovery of 6PPD and 4-ADPA.
