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, 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.
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.
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.
recent progress in the rubber antioxidants Rubber Auxiliary Agent
separately, 4-(dimethyl-butyl amino)diphenylamine (6ppd), another widely used antioxidant in the rubber industry, a recent study reported that the 6ppd (or already converted 6ppd-quinone) released from the tires reacts to form 6ppd-quinone, which is toxic to coho salmon and causes mass coho salmon deaths in the u.s. pacific northwest [59].
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.
rubber antioxidants and chemical 6ppd
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).
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
- Is 6PPD a toxic oxidant?
- To enhance tire durability, the antioxidant N- (1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) is used in rubber, but it converts into the toxic 6PPD quinone (6PPD-Q) when exposed to oxidants like ozone (O 3), causing ecological concerns.
- 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).
- Can 6PPD be removed from end-of-life tires?
- We introduce a decontamination strategy that removes 6PPD from end-of-life tires before it enters the broader ecosystem. We demonstrate the catalytic upgrade of 6PPD to safe chemicals and the valorization of crumb rubber to aromatics and carbon black using microwave-assisted pyrolysis.

- Why are P-phenylenediamines added to tire rubber?
- Rubber-derived tire chemicals (RDCs) are an important source of environmental pollutants in urban cities owing to the increasing demand and global production of private cars. p-phenylenediamines (PPDs), a class of antioxidants, are added to tire rubber to prevent cracking and thermal oxidative degradation and to extend service life .
