4010na rubber antioxidant: enhancing durability and performance,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 considerations for commercial procurement. what is 4010na? 4010na, also known as.
synthesis and properties of a novel reactive and low-migration
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). the product was characterized by fourier-transform.
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.
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.

synthesis and anti-aging property in acrylonitrile-butadiene rubber of,meanwhile, hpamam and 3.0 g pamam showed better extraction resistance in nbr vulcanizates than 4010na, thus indicating superior anti-aging performances. maximum service temperatures (t max ) under 30 years of service life span of nbr vulcanizates containing hpamam and 3.0 g dpamam were 219°c and 221°c, 15°c and 17°c higher than that of sample with 4010na respectively.
- 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).
- What is the difference between antioxidants 4020 and 4010na?
- 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.
- 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.
- 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:
