Ammonium Pyrophosphate (APP) is a high-purity inorganic phosphate produced through the controlled thermal condensation of ammonium salts and phosphate compounds. It features excellent solubility, strong buffering capacity, and reliable chemical stability, making it suitable for a wide range of industrial, catalytic, flame-retardant, electrochemical, and specialty chemical applications.
APP is commonly used as a phosphate source, catalyst intermediate, flame-retardant component, polymer additive, and fertilizer intermediate. Its reactivity and compatibility with both aqueous systems and solid formulations make it a versatile material for advanced manufacturing and industrial processes.
