Rubber Antiageing Antiage Antioxidant 4020/6PPD price,this study revealed that sunlight-induced transformation of 6ppd could be an important origin of 6ppd-q in aquatic environments, providing significant insights to the potentially underestimated ecological risks of 6ppd.
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.

6ppd in tire manufacturing ustma,6ppd-quinone, or 6ppd, is a recently discovered transformation product of 6ppd that may form when 6ppd reacts with oxygen or ozone under certain conditions. 6ppd is not used in u.s. tire manufacturing.
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.
Best Price Rubber Antioxidant 6PPD CAS No.: 793-24-8,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...
rubber antioxidants and chemical 6ppd
amine antioxidants are the main rubber antioxidants produced and used in china, of which 6ppd and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq, rd) have the highest production, accounting for more than 80% of the total amine antioxidants.
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 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..
rubber antioxidants and their transformation products,recently, it was reported that the rubber antioxidant n-(1,3-dimethylbutyl)N'-phenyl-p-phenylenediamine (6ppd or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (twps).
- Does 6PPD ozonation pose environmental risks?
- 6PPD, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (TP), 6PPD-quinone (6PPDQ), during exposure to gas-phase ozone. Important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of TPs from 6PPD ozonation.
- 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
- 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).
