widely used good price rubber antioxidant ippd,n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd) is the most widely used antioxidant in automobile tyres and many rubber products. we investigated the impact of 6ppd and 6ppd quinone on acute toxicity, morphol., swimming behavior, heart rate, and oxygen consumption in zebrafish larvae.
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.
transformation products of tire rubber antioxidant 6ppd for sale
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.
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.

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.
rubber antioxidant 6PPD price antioxidant 4020,recently, roadway releases of n,n′-substituted 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.

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.
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.
abiotic oxidative transformation of 6-ppd and 6-ppd quinone,6-ppd is not the only n,n’-disubstituted phenylenediamine that may be added as antioxidant or, specifically, as antiozonant to tires. dppd is also of importance and its ozonation in aqueous phase and gas phase were additionally investigated in this study.
