Aluminum Hypophosphite is an efficient inorganic phosphorus-based halogen-free flame retardant with good thermal stability, high phosphorus content, high flame retardant efficiency, slightly soluble in water and non-volatile. It can be used alone or in combination with other phosphorus and nitrogen-based halogen-free flame retardants such as APP, MPP, MC and metal hydroxide. It is widely used in many fields such as PP, ABS, PC/ABS, PE, TPR, TPE, TPU, EDPM, PA6, PBT and other polymer materials as well as coating adhesives.
