Antioxidant 9228 Molecular formula: C53H58O6P2 CAS NO：154862-43-8 Chemical name: Bis (2,4-dichlorophenyl) pentaerythritol diphosphate

Features and Applications/Product Characteristics

Antioxidant 9228 is a high molecular weight phosphite antioxidant with characteristics such as high temperature resistance, hydrolysis resistance, low volatility, low migration, good thermal stability, high antioxidant efficiency, and high molecular weight and phosphorus content. It has the function of quickly decomposing hydrogen peroxide, protecting the color and transparency of the processing process. Combined with hindered phenolic antioxidants, it improves processing thermal stability and provides long-lasting antioxidant efficacy. Suitable for polyester, polyethylene, polypropylene, polyamide, polyurethane, polyvinyl chloride, polystyrene, polycarbonate, ABS resin, especially suitable for high-temperature processing of polyester, polycarbonate, polyamide, polyphenylene ether, and polyphenylene sulfide. The general dosage is 0.1-0.5%.
