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.
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.

rubber antioxidants: tmq, 6ppd, ippd chemical products,Rubber antioxidant 6ppd, n-1,3-dimethylbutyl-n'-phenyl-p-phenylenediamine, is a synthetic rubber antioxidant widely used in the tire and rubber industry. It prevents degradation caused by heat, oxygen and flex cracking. 6ppd acts as a stabilizer and antiozonant, preventing the formation of harmful free radicals and extending service life
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,the tire antioxidant and antiozonant, 6ppd, is added to extend the polymer rubber lifetime. following environmental exposure, 6ppd transforms to its highly toxic quinone form n (1,3
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.
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 antioxidant 6ppd 4020 793-24-8 manufacturer
rubber antioxidant 6ppd is commonly used in the production of tires, belts, hoses, cables, and other rubber products that are exposed to harsh environmental conditions. it provides superior protection against oxidation and heat aging, helping to extend the service life of rubber products and reduce maintenance costs.
from tread to watershed: how tire wear particle chemicals,the rubber-derived ozone transformation product 6ppd-quinone (6ppd) was discovered in 2020 as a causative agent for urban runoff mortality syndrome in coho salmon.
- What are the effects of 6PPD & 6ppd-q in air and dust?
- Evaluating different Impacts of 6PPD and 6PPD-Q in air and dust. The presence of 6PPD and 6PPD-Q contributes to inhalation hazards by releasing particulate matter and volatile organic compounds into the air. Inhalation of these pollutants poses risks to respiratory health and may lead to various respiratory issues upon exposure.
- Which PPDS are used in pharmacology?
- The annual usage of PPDs, like N- (1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD), N,N′-bis (1,4-dimethylpentyl)-p-phenylenediamine (77-PD), and N,N′-diphenyl-p-phenylenediamine (DPPD), has escalated to significant levels in certain countries, exceeding hundreds of thousands of tons (Lv, 2010; Matsumoto et al., 2013).
- 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.
