rubber antioxidants and their transformation products,in this review, we first summarize the category and application of rubber antioxidants in the world, and then demonstrate the formation mechanism of their tps in the environment, emphasizing their influence on the ozone oxidative degradation.
various external factors, including oxidative agents (such as oxygen), heavy metals, uv rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. this review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
synergistic effects of antioxidant and silica on enhancing
in this work, the thermo-oxidative aging performance of antioxidant n-isopropylN'-phenyl-p-phenylenediamine (4010na)/silica (sio 2)/natural rubber (nr) composite was evaluated by the variations of mechanical properties and chemical structure after aging at 100 ℃.
synthesis and properties of a novel reactive and low,rubber composites containing antioxidants 4020 and 4010na were immersed and extracted, resulting in solutions that were noticeably darker in color than those of the rubber composites with gma-ppda antioxidants, which had also been immersed.

4010na rubber antioxidant: enhancing durability,4010na is a widely used rubber antioxidant that plays a crucial role in improving the durability and performance of rubber products. this article provides an in-depth overview of 4010na, highlighting its characteristics, applications in rubber product manufacturing, compatibility with other products, and essential cons
effectiveness of different kinds of antioxidants in resin
the effectiveness of several antioxidants belonging to different chemical classes such as p-phenylene diamine (antioxidant 4010na), secondary amine (antioxidant 445), quinoline (antioxidant rd), and phenolic (bht, 1010, 2246) on the performance of a resin-cured biir vulcanizate was investigated.
rubber antioxidant 4010na(ippd) price,rubber antioxidant 4010na (ippd) a high activity antioxidant for matural and synthetic rubber provides powerful antiozonant and antioxidant properties with excellent high temperature, fatigue and flex resistance to rubber compounds.

high quality rubber antioxidants 4010na ippd,a combined molecular dynamics (md) simulation and experimental study is presented to investigate the effects of small molecules 4010na, go, and go-4010na on the compatibility and damping properties of nitrile-butadiene rubber (nbr) composites.
- 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.
- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
- 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.
- Why do we need antioxidants for rubber composites?
- Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
