screening p-phenylenediamine antioxidants, their transformation products, and industrial chemical additives in crumb rubber and elastomeric

Screening p-Phenylenediamine Antioxidants, Their Transformation Products, and Industrial Chemical Additives in Crumb Rubber and Elastomeric

Recently, roadway releases of N,N¡ä-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 ...

Rubber Antioxidants and Their Transformation Products: Environmental Occurrence and Potential Impact

Antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. However, recent studies have revealed that their transformation products (TPs) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber ...

transformation products of tire rubber antioxidant 6ppd in heterogeneous gas-phase ozonation: identification and environmental occurrence

Transformation Products of Tire Rubber Antioxidant 6PPD in Heterogeneous Gas-Phase Ozonation: Identification and Environmental Occurrence

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 ...

Antioxidant activity of p-phenylenediamines studied by DSC

In this study, the antioxidant activity of six N, N ¡ä-substituted p -phenylenediamines in polyisoprene rubber (PIR) has been studied. Three of them, i.e., DPPD, 6PPD and IPPD, are commercial antioxidants widely used in the rubber industry. SPPD is an example of a new structure of phenylenediamines which will be commercialised [9].
