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
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 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.
environmental occurrence and toxicity of 6ppd quinone, an,as there are many unanswered questions surrounding 6ppd, further research is needed. this review highlights the importance of including transformation products in regulations for 6ppd, as well as all emerging synthetic chemicals of concern.
saving coho salmon: alternatives for 6ppd in tire manufacturing
6ppd is a critical tire rubber additive due to its high-performing antidegradant prop-erties. due to its demonstrated ecotoxicity, we are aiming to identify chemical alternatives to 6ppd that not only uphold technical functionality, but also minimize human health and environmental hazards.
rubber anti-aging agent antioxidant 6PPD (4020) supplier,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.
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.
new research indicates higher 6ppd migration from silica tire
6ppd is a rubber chemical used to protect the components of tires from attack by ozone and oxygen. over the recent years, researchers have raised environmental concerns over a 6ppd transformation product, 6ppd-quinone (6ppd), which can impact aquatic life, particularly salmon.
environmental profiles, hazard identification for sale,transformation of 6ppd and 6ppd-q in various environmental compartments. the primary sources of 6ppd and 6ppd-q in the environment are tire and road wear particles. in the atmosphere, 6ppd undergoes a reaction with ozone to form 6ppd-q under conditions such as light and high temperature.
