tire-derived contaminants 6ppd and 6ppd-q: analysis, sample,one such chemical is 6ppd-quinone (6ppd-q), a transformation product of the tire antioxidant 6ppd. in urban stormwater runoff 6ppd-q can exceed acute toxicity thresholds for several salmonid species and is being implicated in significant coho salmon losses in the pacific northwest.
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
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 -...
rubber antioxidant 6ppd in tires as a priority product,ustma and its member companies recommended adding 6ppd to the priority products work plan immediately following the december 2020 tian et al. study that suggested a link between coho salmon mortality and a transformation product of 6ppd from tire and road wear particles (trwp) called 6ppd-quinone.
big discount rubber antioxidant 6ppd for tyre
recent findings that 2-anilo-5-[(4-methylpentan-2-yl)amino]cyclohexa-2,5-diene-1,4-dione (6ppd-quinone), the transformation product of a common tire rubber antioxidant, is acutely toxic in stormwater-impacted streams has highlighted the need for a better understanding of contaminants in urban runoff.
q a: stage 1 alternatives analysis for 6ppd in tires,Pure 6PPD is white solid product, and will gradually oxidizing to brown solid when exposed to the air. Industrial product—6PPD is purple brown to black brown granules or flakes, and will slowly caking When the temperature exceeds 35-40℃.
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.
u.s. tire manufacturers association and u.s. geological,6ppd is an antiozonant (chemical) and antioxidant present in all motor vehicle tires on u.s. roads. the chemical serves critical safety and performance functions that protect motor vehicle tires from degradation upon exposure to ozone and oxygen in the air.
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).
6ppd in tire manufacturing ustma,safety is at the core of everything tire manufacturers do and the complex blend of rubber compounds and materials in our products is designed to withstand a wide range of demanding conditions. 6ppd serves an essential safety function in tires as an antioxidant and antiozonant, protecting the components of the tire from attack by ozone, oxygen
