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.
6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
6ppd: its role in tire manufacturing and environmental impact
published oct 19, 2024. 6ppd, or n-(1,3-dimethylbutyl)-n’-phenyl-p-phenylenediamine, is a chemical compound widely used in tire manufacturing. its primary function as an antioxidant enhances tire durability by preventing degradation from environmental factors like heat, oxygen, and ozone. however, recent studies have raised concerns about
environmental profiles, hazard identification for sale,6ppd-q in human samples highlight the need for further research on public health. abstract. 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.
6ppd in tire manufacturing ustma
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.
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.
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...
environmental impact of tire wear: the 6ppd-q Rubber Antioxidant
The compound 6ppd (1,4-phenylenediamine, short for n-(1,3-dimethylbutyl)-21 n'-phenyl-; CAS #793-24-8) is an antioxidant and antiozonant that prevents rubber compounds from degrading due to exposure to oxygen, ozone, and temperature fluctuations. 6ppd is widely used in the tire manufacturing industry to help tires resist degradation..
q a: stage 1 alternatives analysis for 6ppd in tires,6ppd has been widely studied and used in tires as a highly effective antidegradant since the 1960’s. the recent concern regarding 6ppd in tires relates to a newly identified transformation product, 6ppd, and its potential impacts to certain salmonids.
- Does ustma use 6PPD?
- 6PPD is currently used in all USTMA member passenger, light truck, truck and bus radial, and motorcycle tires. USTMA is not aware of any new motor vehicle tires available today that do not contain 6PPD.
- Are there alternatives to 6PPD as a rubber antioxidant?
- Nevertheless, conclusive studies identifying superior alternatives to 6PPD as a rubber antioxidant remain scarce in the current literature. Urbanization has resulted in an increase in surface runoff, a phenomenon that plays a pivotal role in the transportation of chemicals originating from tire wear into aquatic environments.
- What are the data gaps in 6PPD ozonation?
- Important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of TPs from 6PPD ozonation. To address these data gaps, gas-phase ozonation of 6PPD was conducted over 24–168 h and ozonation TPs were characterized using high-resolution mass spectrometry.
- 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).
