end-of-life tire decontamination from 6ppd and upcycling,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 found in tires.
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.

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,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.

the huge consumption of the tire rubber antioxidant n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) has resulted in pervasive contamination in aquatic environments. more importantly, the transformation product of 6ppd, i.e., 6ppd-quinone (6ppd-q), is raising increasing concerns due to its high toxicity to aquatic organisms. however, whether and how 6ppd-q can be formed from 6ppd in.
rubber antioxidants: tmq, 6ppd, ippd chemical products,6ppd, or n-1,3-dimethylbutyl-n’-phenyl-p-phenylenediamine, is a synthetic rubber antioxidant widely used in the tire and rubber industry. it provides protection against degradation caused by heat, oxygen, and flex-cracking. 6ppd acts as a stabilizer and antiozonant, preventing the formation of harmful free radicals and extending the service life of rubber products.

a ubiquitous tire rubber–derived chemical induces acute science,these results reveal unanticipated risks of 6ppd antioxidants to an aquatic species and imply toxicological relevance for dissipated tire rubber residues. humans discharge tens of thousands of chemicals and related transformation products to water ( 1 ), most of which remain unidentified and lack rigorous toxicity information ( 2 ).

6ppd caught on in the global tire market, and it’s been in tire rubber everywhere ever since. “as far as i know, it’s in almost every tire produced in the u.s., if not the world,” said jeremy conkle, a senior chemist and toxicologist with the delaware river basin commission.
