end-of-life tire decontamination from 6ppd and upcycling,abstract. n (1,3-dimethylbutyl)- n ′-phenyl- p-phenylenediamine (6ppd) is a ubiquitous rubber antioxidant and antiozonant that extends the lifetime of common rubber products, such as those.
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. [1] although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance. performance.
6ppd rubber antioxidant: characteristics, applications, combinations
6ppd (6ppd or n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a widely used rubber antioxidant that plays a vital role in the production of rubber products. this article aims to provide an overview of 6ppd, its characteristics, its applications in rubber product manufacturing, potential product combinations, and important considerations for commercial procurement. 1. what is 6ppd? 6ppd.
transformation products of tire rubber antioxidant 6ppd in,6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppdq), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation. to address these data gaps, gas-phase ozonation of 6ppd was.
screening p-phenylenediamine antioxidants, their transformation
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. here, we analyzed tire wear particles (twps), recycled rubber doormats, and turf-field crumb rubbers.
