recent progress in the rubber antioxidants Rubber Auxiliary Agent,while extensive efforts have been directed toward the research of rubber antioxidants, there are still several scientific and technological issues that remain unsolved, and the perspectives on the future trends of rubber antioxidants are highlighted. graphical abstract. download: download high-res image (276kb) download: download full-size image.
transformation products of tire rubber antioxidant 6ppd for sale
6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.

rubber antioxidants and their transformation products,antioxidants are added to natural rubber (nr) and synthetic rubber (sr) during mastication, which is the process of transforming rubber from a strong and elastic state to a soft and plastic state [4, 5]. in addition, they could also be coated on the nr surface to achieve a similar effect [6].
- What are rubber antioxidants?
- Rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . To date, the annual global consumption of rubber antioxidants is over 700,000 tons, accounting for about 40% of the total amount of rubber additives.
- What are the TPS of rubber antioxidants?
- The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
- Can rubber antioxidants contain rare-earth ions?
- The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
- Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
- Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
