Antioxidant 5057 is a liquid hindered amine antioxidant, which not only maintains the excellent antioxidant properties of hindered amine, but also has unique liquid properties, which is easy to measure and transport. Its outstanding characteristics are low volatility and good compatibility, and no dilution is required during the addition process. It has 100% activity. In combination with other functional stabilizers such as 1135, it can play a very good synergistic effect. Can also be used alone. The product has excellent antioxidant properties and is completely suitable for the whole process of polymer preparation and processing. For the stabilization of polyurethane cushion foam, it can effectively inhibit the formation of peroxide during storage and transportation. Further prevent scorch in foaming; In addition, when soft foamed polyurethane is used in industries such as automotive manufacturing, furniture and fiber fabrics, 5057 is added, and its low volatility will avoid staining the fabric. Its properties can be combined with other phenolic antioxidants such as 1135, or with stabilizers (such as phosphite, thioester, hydroxylamine, lactone) and light stabilizers (such as UV absorbers, HALS). Its superior performance can be further developed. Used for polyurethane plastics, fibers, elastomers, etc.
