chemical characteristics, leaching, and stability of the,aqueous leaching simulations from tire tread wear particles (twps) indicated short term release of ∼5.2 μg 6ppd per gram twp over 6 h under flow-through conditions. aqueous stability tests observed a slight-to-moderate loss of 6ppd over 47 days (26 ± 3% loss) for ph 5, 7 and 9.
6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
tire-rubber related pollutant 6-ppd quinone: a review of its
exposure to 6-ppdq at environmentally relevant concentrations could induce several types of toxicity, including neurotoxicity, intestinal toxicity, and reproductive toxicity. this review also identifies and discusses knowledge gaps and research needs for the study of 6-ppdq.
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
tire anti-degradants (6ppd) team itrc itrc
tire anti-degradants are used to extend the life of tires by preventing the cracking and breakdown of rubber as it reacts with ozone over time. 6 p-phenylenediamine (6ppd) is currently the most prevalent chemical used for this purpose and is known to produce 6ppd-quinone (6ppd-q) through interaction with ozone. 6ppd and 6ppd-q enter the
environmental fate of tire-rubber related pollutants 6ppd,there is a linkage between 6ppd-q in soil and tire rubber wear particles (trwps), indicating its origin from sources associated with vehicular activities (klockner et al., 2019). approximately 50% of trwps can infiltrate the soil, releasing bound chemicals like 6ppd (klockner et al., 2019).
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.
environmental profiles, hazard identification for sale,among the various ppd-q compounds identified in tire rubber granules (12 μg/g), rubber crumbles (0.3–25 μg/g), and recycled rubber door mats (11–26 μg/g), 6ppd-q stands out as the most prevalent (zhao et al., 2023b). research indicates that sunlight not only catalyzes the formation of 6ppd-q in trwps but also accelerates its breakdown.

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.
6ppd rubber antioxidant: characteristics, applications,6ppd (n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a highly effective rubber antioxidant with notable characteristics, including excellent heat resistance, anti-flex cracking properties, and compatibility with various rubber types.
