rubber antioxidants and their transformation products,as one of the widespread rubber antioxidants, amine antioxidants (ppds: tmppd, dppd, 6ppd, and 6ppdtz) could react with o 3 (in parts per billion volume levels) in the environment and produce ppd-quinone .
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 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.
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.
Best Price Rubber Antioxidant 6PPD CAS No.: 793-24-8,n-(1,3-Dimethylbutyl)-n-phenyl-p-phenylenediamine (6ppd) is a ubiquitous rubber antioxidant and antiozonant that can extend the service life of common rubber products and can be used as a thermal oxidation stabilizer for polyethylene, polypropylene and acrylic resins.
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.
p-phenylenediamines and p-phenylenediamine quinone,N-(1,3-dimethyl-buty)-N'-phenyl-P-Phenylenediamines (ppds) are widely used in the rubber industry to effectively prevent oxidation of rubber by ozone, inhibit aging of rubber, and improve product application performance and service life (cataldo, 2018, cataldo, 2019, cataldo et al., 2015).
rubber antioxidants and chemical 6ppd
as one of the widespread rubber antioxidants, amine antioxidants (ppds: tmppd, dppd, 6ppd, and 6ppdtz) could react with o 3 (in parts per billion volume levels) in the environment and produce ppd-quinone .
first grade quality 6ppd rubber antioxidant,recently, roadway releases of N-(1,3-dimethyl-buty)-N'-phenyl-P-Phenylenediamine (ppd) antioxidants and their transformation products (tps) received significant attention due to the highly toxic 6ppd-quinone. however, the occurrence of ppds and tps in recycled tire rubber products remains uncharacterized.
