High-temp Antioxidant Antioxidants in all aspects of the application

Antioxidants in all aspects of the application

 With the development of engineering plastics industry, the use of antioxidants is increasingly widespread, increasing demand. Here we introduce the application of antioxidants in different aspects, can be divided into six areas:

    First, the application of polymer materials:

    Antioxidants in polymer materials are effective antioxidants and are effective stabilizers in polyethylene, polyvinyl chloride and polyvinyl ethers. They are resistant to discoloration and mechanical strength loss in polystyrene and its copolymers The role,

    Second, in the rubber industry applications:

    Antioxidant is commonly used in the rubber phenolic antioxidant, natural rubber, butyl, isoprene, ethylene propylene and other synthetic rubber, acrylic and latex products have a protective effect of thermal aging.

 Third, the application of industrial oil:

This product is a variety of petroleum products, excellent antioxidant additives. It is widely used in turbine oil, transformer oil, hydraulic oil, heat transfer oil, brake oil, spindle oil and precision machinery oil, paraffin antioxidant glue.

    Fourth, the application of fuel oil:

    Gasoline, diesel oil containing a small amount of sulfur and nitrogen compounds and olefins and other unstable, oxidized raw rubber, so add this product can improve its stability.

    Fifth, in the food application:

    This product can be used as food additives.

    Six, in the application of drugs:

    Used to prevent rancidity caused by oxidation of animal and vegetable oils and fats, but also for food and cosmetics containing more oil and food and food contact with food grade plastic and packaging synthetic materials, antioxidants.

    In general, the use of antioxidants is still very broad, it can be applied with the polymer materials industry, rubber industry, industry, fuel industry, food and pharmaceutical industry.

What is the role of antioxidants you know? Do not know the words to come and see it!

    1, the synergistic effect between antioxidants.

     A very well-known example is bis cinnamoyl thiodipropionate (DLTDP) or bis-stearoyl thiodipropionate (DSTDP) with sterically hindered phenols, which are thermally stable in certain polymers Sexual aspects of the application. Another important example of synergism is to improve the melt stability of the polyolefin, see a sterically hindered phenolic complex with phosphite.

    2, the use of chain-type antioxidant polymer stability.

    (CB-D) and the chain-chain receptor mechanism (CB-A) were used to study the mechanism of antioxidant intervention chain reaction.

    3, the use of pre-antioxidant high polymer stability.

    The prophylactic or antioxidant can decompose the hydroperoxide without forming free radical intermediates, so that they prevent the decomposition of the chain caused by the decomposition of the hydroperoxide into free radicals.

Antioxidant 405 is an amine antioxidant and is used as a non-contaminating amine antioxidant for chloroprene rubber, styrene-butadiene rubber, butyl rubber, natural rubber, polyurethane and other adhesives. For heat, light, ozone and so on Caused by the aging of the protective effect is good. Can replace the antioxidant D, MB, RD, 264, etc., for the chloroprene rubber effect is particularly significant. The general amount of 0.5 can replace 1.5 copies of antioxidant D or 1.0 copies of antioxidant MB.
