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.
6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), 6PPD is compatible with a wide range of rubber types, including natural rubber and various synthetic rubbers, making it versatile for different formulations.
Best Price Rubber Antioxidant 6PPD CAS No.: 793-24-8
Rubber antioxidant 6PPD, or N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine, is a widely used chemical compound in the rubber industry, particularly known for its effectiveness in preventing oxidative degradation of rubber products.
chemical characteristics, leaching, and stability of the,We report here the fate and transport-related chemical characterization of the recently discovered environmental toxicant 6ppd-quinone (2-((4-methylpentan-2-yl)amino)-5-(phenylamino)cyclohexa-2,5-diene-1,4-dione or "6ppd"). 6ppd is a transformation product of the tire rubber antioxidant 6ppd.
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.
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.
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).
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.

abstract: 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.
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.
- 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.
- Which PPD-Q compounds are found in tire rubber granules?
- 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.
- Does 6PPD react with tire wear particles?
- In another study, a primary molar yield (per mole 6PPD consumed) of approximately 9.7 % was observed for 6PPD-Q formation from pure 6PPD and about 0.95 % from 6PPD within tire wear particles, suggesting that a substantial mass fraction of 6PPD will ultimately react to form 6PPD-Q (Hu et al., 2022).
- Which compounds are found in tire tread particles compared to 6PPD?
- Furthermore, compounds such as N-cyclohexyl-N′-phenylurea, N-methyl-1,1′-bicyclohexyl]-2-amine, and hexakis (methoxymethyl)melamine were identified in tire tread particles and compared to 6PPD for reference (Stack et al., 2023).
