Characteristics and uses：
Antioxidant 445 is an aromatic amine antioxidant with the characteristics of non-coloring, non-blooming, high temperature resistance, extraction resistance, low volatility, low migration, good thermal stability, high antioxidant efficiency, and no impact on vulcanization. , passivated metal ions and other properties. Suitable for polyethylene, polypropylene, polyurethane, polyvinyl chloride, ABS resin, lubricants, adhesives, elastomers, especially acrylic rubber, ethylene acrylate rubber, neoprene rubber, nitrile rubber, hydrogenated nitrile Rubber, EPDM rubber.
Antioxidant 445 is used in neoprene cable sheaths to improve processing thermal stability and provide long-term antioxidant performance. Used in polyether polyols to increase the oxidation induction temperature and inhibit core burning and yellowing at high temperatures. The general dosage is 0.1-0.5%.
Suitable for: resistance to thermal oxidation at high temperatures. It shows excellent performance during high-temperature processing of polymers, and shows a strong synergistic effect with phenolic and phosphite antioxidants. It belongs to the category of resistance to thermal oxidation. An excellent choice for oxygen formulations. It is especially suitable for protecting neoprene, acrylic rubber, nitrile rubber, EPDM rubber, natural rubber, polyether polyol, etc. from aging caused by high heat and light.
