environmental chemical rubber antioxidants
2.1. amine antioxidants amine antioxidant is the most common rubber antioxidant, which was produced as early as the 1970s and widely used in the rubber industry. typical amine antioxidants include diaryl-secondary amine, acetone-amine condensation product, p-phenylenediamine, and aldehyde-amine condensation product antioxidants [].

performance characteristics of rubber additives and its application price
antioxidant 3100 has one or two compatibilizing genes introduced into the benzene ring on both sides of the molecular structure, so its solubility in rubber increases, the amount in rubber can be increased, and the application of antioxidants 4010na and the defect
recent progress in the rubber antioxidants price,in this review, we systematically review the recent progress of antioxidants for rubber. we first give a brief introduction of the oxidation process and oxidation mechanism for rubbers. then, we present the strategies to improve the anti-oxidative efficiency of rubber antioxidants. after that, recent advances to minimize the blooming and.
rubber antioxidant tmq (rd) 26780-96-1 manufacturer
rubber antioxidant tmq(rd); cas no. 26780-96-1 ; molecular formula: c12h15n; other synonyms: 2,2,4-trimethyl-1,2.high heat resistance, low volatility, and compatibility with a wide range of other additives and materials. with its exceptional oxidation.
screening p-phenylenediamine antioxidants, their transformation,recently, roadway releases of n,n′-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.
- 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.
- Which country produces the most rubber antioxidants?
- China is one of the main countries producing rubber antioxidants, and the production accounts for more than 70% of the total amount globally. The production of rubber antioxidants in China ranged from 365,000 to 378,000 tons during 2016–2020, showing a constant annual trend [ 12 ].
- 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
- Are rubber antioxidants a rational design?
- The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
