    Aluminum hypophosphate is a new type of flame retardant with good thermal stability and does not cause polymer decomposition during processing,
    It also does not affect the plastic molding composition. This product is slightly soluble in water and does not evaporate under the usual conditions for preparing and processing thermoplastic polymers. Make its application products have high thermal stability, good mechanical properties and good weather resistance during processing. Polymer compositions containing aluminum hypophosphate exhibit high flame retardancy. According to UL94 standard, the thickness is 0.7 mm, and its flame retardancy level is VO. According to IEC61335-1 standard, at 800 ℃, the thickness is greater than 0.8mm, and it has passed GWIT testing. All of them have passed various flame retardancy level tests. Due to the high phosphorus content of aluminum hypophosphate, It has advantages such as good thermal stability, low water solubility, and high flame retardancy. It was developed by Blue Chemical in the United States and used on PET, achieving high flame retardancy. When added to PET, the heat release rate and the heat generated during combustion sharply decrease, and the amount of carbon formed after combustion increases. The flame retardancy reaches UL94 standard V-0 level. Moreover, through experiments, compared to the PET flame retardants currently used in China, the flame retardancy has been improved by 60%, and the cost has been reduced by 35%.
