chemical characteristics, leaching, and stability of the,aqueous leaching simulations from tire tread wear particles (twps) indicated short term release of ∼5.2 μg 6ppd per gram twp over 6 h under flow-through conditions. aqueous stability tests observed a slight-to-moderate loss of 6ppd over 47 days (26 ± 3% loss) for ph 5, 7 and 9.
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.
transformation products of tire rubber antioxidant 6ppd for sale
6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
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 their transformation products
amine antioxidants are the main rubber antioxidants produced and used in china, of which 6ppd and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq, rd) have the highest production, accounting for more than 80% of the total amine antioxidants.
a tire industry perspective on 6ppd replacement: the challenge,to act like 6ppd, a drop-in substitute must: function as antiozonant and antioxidant to help prevent the degradation and cracking of rubber compounds (unsaturated elastomers) by protecting against ozone attack, oxidation, and heat aging.

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...
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.
