Specification :

AMMONIUM POLYPHOSPHATE ( APP-a)

Molecular formula: ( NH4PO3) n n> 1000
Model No.: TFAPP02
Properties:
Ammonium ployphosphate ( TFAPP02) is a non-halogen flame retardant. It acts as flame retardant by intumescence mechanism. When TFAPP02 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 phosphate ester, a carbon foam is built up on the surface and acts as an insulation layer.
