Application
  • It acts as a flame retardant by the intumescence mechanism. When APP-II 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 phosphate ester. Following dehydration of the phosphate ester, a carbon foam is built upon the surface and acts as an insulation layer.
  • It's widely used in coating, painting, adhesives, sealants, plastic masterbatch, and rubber.
