computational studies of rubber ozonation explain the effectiveness of,the discovery that the commercial rubber antidegradant 6ppd reacts with ozone (o3) to produce a highly toxic quinone (6ppdq) spurred a significant research effort into nontoxic alternatives. this work has been hampered by lack of a detailed understanding of the mechanism of protection that 6ppd affords rubber compounds against ozone. herein, we report high-level density functional theory.

recent progress in the rubber antioxidants price,in this review, we summarized the recent advances in rubber antioxidants over the last 10 years and offered some perspectives to outline the challenges and future research directions for the rubber antioxidants. 2. brief introduction of the oxidation process and oxidation mechanism of the rubbers.
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.

- Can antioxidants prevent rubber aging?
- The addition of antioxidants to rubber is one of the most economical and effective methods for delaying rubber aging. However, antioxidant migration can cause environmental pollution. To address this issue, a new reactive antioxidant was synthesized via the chemical bonding of glycidyl methacrylate (GMA) and p -aminodiphenylamine (PPDA).
- Why is the rubber antioxidant market growing?
- The rubber antioxidant market is expected to expand significantly in the future due to the increasing demand for antioxidants in the manufacture of various rubber products used in the tire industry, automotive industry, and others. However, many commercial antioxidants are plagued with blooming/migration issues, toxic nature
- 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.
- What is thermo-oxidative aging of rubber?
- This review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers. The oxidative degradation of rubber proceeds by a free-radical chain reaction mechanism . As shown in Fig. 1a, rubber aging processes have three distinct phases: (i) Initiation, (ii) Propagation, and
