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.
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, 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,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
n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd) is commonly used in rubber compounds as antioxidants to protect against degradation from heat, oxygen, and ozone exposure. this practice extends the lifespan of rubber products, including tires, by preventing cracking, aging, and deterioration.
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.

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.
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
phosphite antioxidants mainly include tris (nonylphenyl) phosphate (tnp), tris (1,2,2,6,6-pentamethylpiperidinyl) phosphite (gw-540), and tris (2,4-di-tert-butylphenyl) phosphite (irgafos168). gw-540 is widely used in tires blended with styrene butadiene rubber and polybutadiene rubber.
6ppd in tire manufacturing ustma,ustma mobilizes a consortium of 16 tire manufacturers to conduct an alternatives analysis for 6ppdin tires after a decision by dtsc to act on ustma’s recommendation to list 6ppd in tires as a priority product under the state’s safer consumer products (scp) program.
- Is 6PPD in tires a priority product?
- DTSC designates 6PPD in tires as a Priority Product and USTMA expands its consortium to 32 tire manufacturers from around the world to prepare a Preliminary (Stage 1) Alternatives Analysis (AA) to identify and evaluate potential alternatives to 6PPD in tires. Individual consortium members submitted the report to DTSC to meet compliance deadline.
- Is there an alternative to 6PPD in tires?
- Today there is no commercially available alternative to 6PPD that both provides comparable safety and performance in motor vehicle tires and minimizes potential environmental effects. 6PPDQ Identified | USTMA requests DTSC review 6PPD in tires
- 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 causes 6ppd-q in soil and tire rubber wear particles (TRWPS)?
- 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).
