transformation products of tire rubber antioxidant 6ppd for sale,6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), 6PPD is compatible with a wide range of rubber types, including natural rubber and various synthetic rubbers, making it versatile for different formulations.
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 antioxidants and their transformation products
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 [31].
widely used chemical rubber antioxidant ippd,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.

global rubber antioxidant ippd market research report 2024
antioxidant 4010na (ippd) is recommended for use in latex, natural and synthetic rubber. the global rubber antioxidant ippd market was valued at us$ million in 2023 and is anticipated to reach us$ million by 2030, witnessing a cagr of %during the forecast period 2024-2030.
new evidence of rubber-derived quinones in water, air for sale,by investigating this phenomenon, we identified a highly toxic quinone transformation product of n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd), a globally ubiquitous tire rubber antioxidant.
improvements of lanthanum complex on the thermal-oxidative
mixed antioxidants composed of antioxidant ippd and novel rare earth lanthanum complex were used as an additive to prepare natural rubber (nr) samples. the variations of macro-properties, surface characterizations, and internal groups were investigated by mechanical testing, x-ray photoelectron spectroscopy, and thermogravimetric analysis
p-phenylenediamines and p-phenylenediamine quinone,in addition to wear of rubber tires, our research indicates that rubber coatings on cables and daily use of rubber consumer products also release ppds and ppd-qs, which requires attention. we describe a three-step oxidation scheme for the conversion of 6ppd to 6ppd-q in the environment.
rubber common contact allergens wiley online library
n‐isopropyl‐n'‐phenyl‐p‐phenylenediamine (ippd) is an antioxidant used in rubber production to reduce the effects of perishing by atmospheric oxygen. the prevalence of rubber contact allergy is equivalent between males and females.
recent progress in the rubber antioxidants Rubber Auxiliary Agent,recent advances in the blooming/migration issues for rubber antioxidants. 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.
- What are rubber antioxidants?
- Rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . To date, the annual global consumption of rubber antioxidants is over 700,000 tons, accounting for about 40% of the total amount of rubber additives.
- How many rubber antioxidants are produced in China?
- China is one of the main countries producing rubber antioxidants, and the production accounts for more than 70% of the total amount globally. The production of rubber antioxidants in China ranged from 365,000 to 378,000 tons during 2016–2020, showing a constant annual trend .
- How does a rubber matrix affect antioxidative performance?
- Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
- 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].
