a tire industry perspective on 6ppd replacement: the challenge,some tire wear and lifetime considerations. part of tread wear is thermal-mechanical-oxidative degradation of the tread compound. less effective substitute will lead to more tire road wear particles.
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 found...
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), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.
big discount rubber antioxidant 6ppd for tyre,recent findings that 2-anilo-5- [ (4-methylpentan-2-yl)amino]cyclohexa-2,5-diene-1,4-dione (6ppd-quinone), the transformation product of a common tire rubber antioxidant, is acutely toxic in stormwater-impacted streams has highlighted the need for a better understanding of contaminants in urban runoff.

environmental impact of tire wear: the 6ppd-q Rubber Antioxidant,the compound 6ppd (short for 1,4-benzenediamine, n-(1,3-dimethylbutyl)- 21 n’-phenyl-; cas #793-24-8) is an antioxidant and antiozonant that prevents degradation of rubber compounds caused by their exposure to oxygen, ozone and temperature fluctuations. 6ppd is widely used in the tire manufacturing industry to help tires resist degradation and
rubber antioxidants and their transformation products
antioxidants are added to natural rubber (nr) and synthetic rubber (sr) during mastication, which is the process of transforming rubber from a strong and elastic state to a soft and plastic state [4, 5]. in addition, they could also be coated on the nr surface to achieve a similar effect [6].
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.
rubber antioxidants and chemical 6ppd
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 organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber
rubber antioxidants: tmq, 6ppd, ippd chemical products,antioxidant tmq . tmq, also known as polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, is a widely used rubber antioxidant. it provides excellent protection against heat, oxygen, and flex-cracking, enhancing the durability and performance of rubber products.
- 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.
- Is 6PPD a toxic oxidant?
- To enhance tire durability, the antioxidant N- (1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) is used in rubber, but it converts into the toxic 6PPD quinone (6PPD-Q) when exposed to oxidants like ozone (O 3), causing ecological concerns.
- What are P-phenylenediamines in tires?
- One category of these chemicals is p-phenylenediamines (PPDs), which serve as antioxidants and are added to tire rubber to prevent cracking, and thermal oxidative degradation, and to prolong the tire lifespan (Hough et al., 2020).
- Why is acetone better than 6PPD?
- Acetone’s lower boiling point (56 °C) compared with 6PPD (260 °C) makes solvent recovery much less energy intensive. Although acetone can readily dissolve many classes of molecules 25, it does not degrade the cross-linked rubber phase. This is crucial for producing a 6PPD-free crumb rubber product that is safe for various applications.
