Aluminum Hypophosphite (AHP) is a high-efficiency, halogen-free flame retardant belonging to the inorganic phosphinate class.

It is widely recognized for its exceptional thermal stability, high phosphorus content (typically??40%), and minimal impact on the mechanical properties of base materials. With a decomposition temperature exceeding 290?C320??C, AHP is particularly suitable for high-temperature engineering plastics and polymers, making it a premium choice for flame-retardant modifications in demanding industries such as electronics, automotive, and construction.
