Ammonium polyphosphate

  (CAS: 68333-79-9)

  Product features:

  Ammonium Polyphosphate is an environment-friendly, non-toxic and halogen-free flame retardant additive, the formula is (NH4PO3)n. APP is an inorganic salt of polyphosphoric acid and ammonia.

  APP is a stable, non-volatile compound. When APP is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia. The polyphosphoric acid reacts with hydroxyl groups to form a nonstable phosphateester. Following dehydration of the phosphateester, a carbon foam is built up on the surface and acts as an insulation layer.
