recent progress in the rubber antioxidants price,the antioxidative effect of silica-s-tp for rubber composite is superior to for the traditional antioxidants such as 4020, rd, 2246 and 264, and the high efficiency free radical capturing activity of silica-s-tp was stem from the polyphenol on the silica surface.
obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to

doi: 10.1016/j.cclet.2024.109669 corpus id: 267950246; growth of ceco-mof in dendritic mesoporous organosilica as highly efficient antioxidant for enhanced thermal stability of silicone rubber
antioxidant modified graphene oxide for robust and highly,2,2,4-trimethyl-1,2-dihydroquinoline polymer ((c12h15n) n, n = 2–4), known as antioxidant rd, is a ketone amine antioxidant for rubber. antioxidant rd can provide excellent protection of oxidation of rubber that caused by thermal-oxidative aging and catalytic oxidation by metal ions [7]. given that go has many carbonyl groups that can.
rubber antioxidants and their transformation products
rubber is a group of high-molecular-weight polymer materials with a property of elasticity at 20–27 °c , and rubber is one of such typical commercial products. rubber products are mainly used in industrial and agricultural production, transportation, and national defense construction, and antioxidants are a group of the most important.
tmq antioxidant for rubber industry: enhancing performance,in the realm of rubber manufacturing, the utilization of effective rubber additives is crucial to ensure superior product quality and longevity. one such essential rubber additive is the antioxidant tmq, also known as rd. in this article, we will delve into what tmq is, its role in rubber product production, and the advantages it holds over other similar products in the market. tmq antioxidant.
effect of thermo-oxidative aging on thermal elongation
antioxidant c with a smaller molecular weight (m w =358.5 g/mol) has more hydroxyl groups per unit mass (n c-oh =0.0056 n a) and the lowest steric hindrance compared with antioxidants a and d [39]. therefore, antioxidant c with better oxidation resistance has a greater influence on the thermal elongation results and lower elongation values.

- Which rubber antioxidants are used in China?
- Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
- 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) .
- Does antioxidant 2246 protect rubber from aging?
- Among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. Because hydrogen in phenolic antioxidants can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21, 22].
- 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 .
