      Antioxidants are important additives used in various industries to prevent oxidative degradation of materials. They are particularly important in polymers, lubricants and food products.

      Product performance

      7 Jan 2019
      Oxidation Inhibition: Antioxidants effectively inhibit the oxidation process, which can cause material degradation, discoloration or loss of mechanical properties.
      Enhanced Durability: Antioxidants can significantly extend the life of your product by preventing oxidative degradation.
      Thermal Stability: Many antioxidants also provide thermal stability, ensuring the material can withstand high temperatures without degrading.
      Compatibility: They are compatible with a wide range of polymers, oils and other materials, making them suitable for a variety of applications.

      Principles of Action

      7 Jan 2019
      Antioxidants work primarily through two mechanisms:
      Primary Antioxidants (Free Radical Scavengers): These compounds, such as hindered phenols and aromatic amines, neutralize free radicals formed during oxidation. By donating hydrogen atoms, they convert free radicals into more stable, non-reactive species.
      Second Antioxidants (Peroxide Decomposers): These compounds, such as phosphites and thioesters, break down hydroperoxides into non-radical, stable products. This prevents hydroperoxides from decomposing into free radicals, thereby inhibiting oxidative chain reactions.

      App

      7 Jan 2019
      Antioxidants are incorporated into the material during the manufacturing process. The concentration and type of antioxidant used depends on the specific requirements of the application, such as expected exposure to oxidative conditions, the type of polymer or material, and the desired service life of the product.
      Plastics and Polymers: Used in polyethylene, polypropylene, PVC and other polymers to prevent oxidative degradation during processing and end use.
      Rubber: Added to rubber compounds to prevent oxidative aging, which can lead to embrittlement and loss of elasticity.
      Lubricants and Fuels: Added to oils, greases and fuels to prevent oxidation, which can lead to sludge formation, increased viscosity and acid build-up.
      Food Industry: Used in food packaging and food to prevent oxidation, which can lead to rancidity and loss of nutritional value.
      Cosmetics: Added to skin care products and cosmetics to prevent oxidation of active ingredients and ensure product stability and efficacy.
      Adhesives and Sealants: Used to maintain the performance and durability of adhesives and sealants exposed to oxidative conditions.

      in conclusion

      Antioxidants are essential for improving the durability and performance of materials exposed to oxidative conditions. By understanding their properties, principles of action and applications, industries can effectively utilize these additives to produce high-quality products that last longer.
