GreatBay XZ-EF002

                                                    Ammonium polyphosphate

Chemical name: Ammonium polyphosphate
Brand name: GreatBay XZ-EF002
Equivalent brand: Exolit AP 422
Molecular formula:
(NH4PO3)n  n>1000
Properties:
Ammonium polyphosphate (XZ-EF002) is a non-halogen flame retardant. It acts as flame retardant by intumescence mechanism. When XZ-EF002 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.
