environmental profiles, hazard identification for sale,the primary toxic substance responsible for this phenomenon is identified as 6ppd-q, a conversion product of the antioxidant 6ppd commonly added to tire formulations to protect rubber polymers from ozone damage (greer et al., 2023a, mcintyre et al., 2021). one notable example of this issue is the rain-related urban runoff mortality syndrome
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 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.
eco-friendliness rubber antioxidant tmq for tire,tian et al. found that 6ppd-quinone, a derivative of tire antioxidant 6ppd, can cause acute death of silver salmon (tian et al. 2021). many recent studies have demonstrated the hazards of the extensive use of tire antioxidants.
saving coho salmon: alternatives for 6ppd in tire manufacturing
6ppd is a critical tire rubber additive due to its high-performing antidegradant prop-erties. due to its demonstrated ecotoxicity, we are aiming to identify chemical alternatives to 6ppd that not only uphold technical functionality, but also minimize human health and environmental hazards.
from tread to watershed: how tire wear particle chemicals,recent studies have demonstrated the widespread occurrence and toxicity of trwps and their associated chemicals (e.g. 6ppd, 6ppd-quinone, benzothiazoles, phthalate esters, polycyclic aromatic hydrocarbons, etc.) in both aquatic and terrestrial environments.

specifically, their research has linked certain chemicals in tire particles, such as n-(1,3-dimethylbutyl)-n´-phenyl-p-phenylenediamine (6ppd)—an antioxidant that stops tires from degrading—to mass die-offs of fish.
first grade quality 6ppd rubber antioxidant,here, we analyzed tire wear particles (twps), recycled rubber doormats, and turf-field crumb rubbers for seven ppd antioxidants, five ppd-quinones (ppdqs), and five other 6ppd tps using liquid chromatography-tandem mass spectrometry.
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
rubber antioxidants and their transformation products,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 .
- What is 6PPD used for?
- 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. [ 1 ] Although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance. It is one of several antiozonants based around p -phenylenediamine.
- 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.

- Is 6PPD a toxicity hazard?
- However, this same property facilitates the transfer of 6PPD and its oxidation products into the environment as tire-wear debris. The 6PPD-quinone (6PPD-Q, CAS RN: 2754428-18-5) is of particular and increasing concern, due to its toxicity to fish.
- Why is Santoflex 6PPD better than IPPD?
- Santoflex™ 6PPD gives better long term fatigue resistance and ozone protection than IPPD. Due to its specific molecular structure and higher rubber solubility, it is less affected by environmental variables, such as heat or leaching, leading to greater durability.
