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.
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.

leveraging high-resolution mass spectrometry, we identified 19 probable 6ppd-derived tps in both ozonated 6ppd and twp samples, underscoring formation of diverse tps from this antioxidant. by screening environmental samples, nine 6ppd-derived tps were detected within roadway runoff. the data confirm that when tire rubber antioxidants react
end-of-life tire decontamination from 6ppd and upcycling nature,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.
environmental fate of tire-rubber related pollutants 6ppd
the global production and consumption of rubber antioxidants have gone high, almost passing the phosphorus flame retardants (wu et al., 2020). 6ppd dominates the antioxidant production, typically present in rubber materials at 0.4–2% levels (zhang et al., 2022; zhao et al., 2023). 6ppd can act with ozone during the driving processes and thus.
The latest development of rubber antioxidants,currently, rubber antioxidants are one of the indispensable additives in the rubber industry, they enhance the service life and reliability of the rubber product by protecting it from degradation. unfortunately, antioxidative efficiency, toxicity, and blooming/migration issues, etc., have plagued the development of rubber antioxidants.

as we advance into 2024, the role of antioxidants in rubber manufacturing remains crucial. one such critical antioxidant is n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd). this article provides a comprehensive overview of 6ppd, comparing it with other rubber antioxidant types and discussing their applications in various industries.
p-phenylenediamines and p-phenylenediamine quinone,the ppds and ppd-qs components were compared between the resolved factors and related rubber product extracts. factor 1 had high loads for 6ppd, ippd, dppd, and 6ppd-q and was considered a source of car tires. 6ppd has been identified as the main ppd in tire wear particles (zhao et al. 2023). factor 2 had a high load for cppd.
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.

- Are rubber antioxidants toxic?
- Recent advances in the toxicity issue of rubber antioxidant With the increasing popularity of automobiles, tire wear particles, generated from tire material during use on roads, would ultimately enter the eco-system, such as soil, aquatic environment, etc .
- What are the future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
- Does 6PPD ozonation pose environmental risks?
- 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.
- How can Antioxidants improve the antioxidative capacity of the rubber matrix?
- Generally speaking, as shown in Figs. 2 and 3, there are two main strategies to improve the antioxidant's antioxidative capability for the rubber matrix: (i) using two or more antioxidants together, and (ii) molecular design of antioxidants. Fig. 2.
