improving thermal-oxidative aging resistance of styrene-butadiene,the antioxidant n-isopropyl-n′-phenyl-p-phenylenediamine (4010na) was dissolved in ethanol and impregnated into silica aerogel (sag) via vacuum-pressure cycles, yielding composite particles (a-n) with enhanced sustained-release and reinforcing capabilities. the effect of a-n on the mechanical properties and thermal-oxidative aging resistance of styrene-butadiene rubber (sbr) vulcanizates was.

antioxidant 4010na Rubber Products price
details. executive standard: gb/t 8828-2003. [performance] natural rubber, synthetic rubber and latex with excellent general antioxidant, excellent protective properties of ozone cracking; also the heat, oxygen, light and aging two protective agent. this product can also be used independently, but also with paraffin wax or other antioxidant and.
influence of the molecular structure of phenylamine antioxidants on,structure of antioxidants significantly affects the anti-migration and thermal-oxidative aging properties.and thermal-oxidative aging properties of nitrile butadiene rubber (nbr) composites.
introduction of rubber antiaging agent and its types and functions
there are anti-aging agent ndbc, anti-aging agent ndibc, anti-aging agent ndmc. all green powder. with good ozone resistance and thermal oxidation resistance, expensive (due to nickel on the earth less storage, but a wide range of uses), but also a certain toxicity, deep color, easy to spray frost, not suitable for light color rubber products, in the rubber industry consumption is very few.
synergistic effects of antioxidant 4010na ippd,although there are a variety of industrial antioxidants on the market at present, n, n′-substituted p-phenylenediamines are one of the most widely used as antioxidants in rubber industry [28].some studies about anti-oxidation activity of n, n′-substituted p-phenylenediamines have been reported, nevertheless, most of the papers evaluated their anti-oxidation activity by experimental methods.
anti-aging agents for rubber products supplier
there aremany kinds of antioxidants for rubber products, and each antioxidant has several anti-aging effects at the same time. according to the chemical structure, they can be divided into: amines.
recent progress in the rubber antioxidants price,in this review, we summarized the recent advances in rubber antioxidants over the last 10 years and offered some perspectives to outline the challenges and future research directions for the rubber antioxidants. 2. brief introduction of the oxidation process and oxidation mechanism of the rubbers.
- What causes oxidative aging of rubber?
- 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.
- Does aging time affect mechanical properties of NR composites?
- The mechanical properties are one of the most significant performance parameters in the practical application of rubber material, thus it is essential to detect the variation in mechanical properties of NR composites with increasing aging time.
- 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.
- Does antioxidant 4010na and silica enhance thermo-oxidative aging assistance?
- In this work, the synergistic effects of antioxidant 4010NA and silica on enhancing thermo-oxidative aging assistance for NR were investigated by experiments and molecular simulations, and the mainly conclusions were generalized as follows:
