rubber anti-aging agent antioxidant 6PPD (4020) supplier,6ppd is an organic chemical widely used as stabilising additive (or antidegradant) in rubbers, such as nr, sbr and br; all of which are common in vehicle tires. although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance.
n-(1,3-dimethylbutyl)N'-phenyl-p-phenylenediamine (6ppd) is a ubiquitous rubber antioxidant and antiozonant that extends the lifetime of common rubber products, such as those...
transformation products of tire rubber antioxidant 6ppd for sale
6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
big discount rubber antioxidant 6ppd for tyre,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.
tire-rubber related pollutant 6-ppd quinone: a review of its
the antioxidant 6-ppd has been widely used to prevent cracking and thermal oxidative degradation and to extend the service life of tire rubber. 6-ppd quinone (6-ppdq) is formed via the reaction of 6-ppd with o 3. due to its acute lethality in coho salmon, 6-ppdq has become an emerging pollutant of increasing concern.
environmental fate of tire-rubber related pollutants 6ppd,To improve tire durability, the antioxidant n-(1,3-dimethylbutyl)-n-phenyl-p-phenylenediamine (6PPD) is used in rubber, but when exposed to oxidants such as ozone (O3), it is converted into toxic 6PPD quinone (6PPD-Q), causing ecological problems.

this study revealed that sunlight-induced transformation of 6ppd could be an important origin of 6ppd-q in aquatic environments, providing significant insights to the potentially underestimated ecological risks of 6ppd.
transformation products of tire rubber antioxidant 6ppd for sale,abstract: 6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.
rubber antioxidants: tmq, 6ppd, ippd chemical products
Rubber antioxidant 6ppd, n-1,3-dimethylbutyl-n'-phenyl-p-phenylenediamine, is a synthetic rubber antioxidant widely used in the tire and rubber industry. It prevents degradation caused by heat, oxygen and flex cracking. 6ppd acts as a stabilizer and antiozonant, preventing the formation of harmful free radicals and extending service life

- What is the content of 6PPD in rubber?
- Typically, the content of 6-PPD in rubber materials ranges from 0.4% to 2% . During its production and use, 6-PPD can be transported to exposed surfaces and enter the environment. These antioxidants are highly reactive to ozone . 6-PPDQ is more stable than 6-PPD.
- Which phosphorus flame retardant produces the highest amount of rubber antioxidants?
- The production and consumption of rubber antioxidants have been increasing globally in recent years and are much higher than the consumption of phosphorus flame retardants . 6-PPD produces the highest amount of rubber antioxidants compared to other antioxidants .
- Can 6PPD be removed from end-of-life tires?
- We introduce a decontamination strategy that removes 6PPD from end-of-life tires before it enters the broader ecosystem. We demonstrate the catalytic upgrade of 6PPD to safe chemicals and the valorization of crumb rubber to aromatics and carbon black using microwave-assisted pyrolysis.

- What solvent is used to remove 6PPD from EOL tires?
- Through batch extraction analysis and computational calculations, acetone is the best suited solvent for 6PPD removal from EOL tires of those tested. Furthermore, the batch extraction kinetics follow a first-order profile.
