Ammonium Polyphosphate

APP is an inorganic salt of ammonium and polyphosphoric acid. Ammonium polyphosphate, commonly abbreviated as APP, is a chemical compound that plays a crucial role as a flame retardant and smoke suppressant in various industries. It is known for its ability to enhance fire safety by reducing the flammability of materials. APP is primarily employed as a flame retardant. When exposed to heat or flames, it undergoes an endothermic decomposition, releasing ammonia (NH₃) and phosphoric acid (H₃PO₄). This process helps dilute flammable gases and suppresses combustion.
