preparation of epoxidized natural rubbers with improved aging,our experimental results demonstrated that the non-migratory anti-aging agents can endow rubbers with better resistance to thermo-oxidative aging than the conventional antioxidants with a same amount.
the tensile strength retention, elongation at break retention and aging coefficient (fig. 4 h–j) for the rubber composites revealed that dtsm could endow the rubber with superior thermo-oxidative aging resistance performance compared to antioxidant bht or dt.

the applying of silica-s-tp to enhance the thermal-oxidative stability and ultraviolet light (uv) aging resistance of styrene-butadiene rubber (sbr) was evaluated.
Factory Hot Sale Rubber antioxidant In Stock,in this study, we chose natural rubber (nr) as a matrix and provided a screening strategy based on diverse natural phenolic antioxidants to evaluate their ability in protecting nr composites. thymol, α-tocopherol, and lipid-soluble epigallocatechin gallate (lsegcg) were chosen from 18 natural phenolic antioxidants as potential alternative
antioxidant effects on curing/processing and thermo-oxidative
with anti-aging agents, the hardness of composites decreased while the elongation at break increased. the antioxidants exhibited a lubricating effect which improved the processing fluidity of rubber. when the composites were used at 100 ℃, the anti-aging agent dapd showed the best protective effect on nbr/fe 3 o 4 /zdma composites.
synthesis and properties of a novel reactive and low,antiaging agents react primarily with the free radicals or hydrogen peroxide generated during rubber aging. (10) this reaction reduces the number of free radicals and potentially prevents the formation of active peroxide free radicals, which, in turn, slows the process.

the complexity of thermo-oxidative aging factors along with the lack of quantitative tools significantly hampers its applications. so, building a screening strategy to quickly and easily find an appropriate and eco-friendly ao is imperative. in this study, we chose natural rubber (nr) as a matrix and provided
rubber antioxidants and their transformation products,antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental

... amine and phenolic antioxidants are commonly used in rubber anti-aging systems [10] [11] [12] [13]. compared to the amine antioxidant, phenolic antioxidants are suitable for colorless or...
recent progress in the rubber antioxidants Rubber Auxiliary Agent,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.
- 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 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.
- 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) .
- Are rubber antioxidants harmful to human health?
- As shown in Table 1, many commonly used rubber antioxidants are damaging to human health and the environment. For example, the antioxidant MB Antioxidants are indispensable additives in the rubber industry as they enhance the reliability and service life of the rubber product by protecting it from degradation.
