Holagen-Free APP Ammonium Polyphosphate Flame Retardant For Steel
Ammonium polyphosphate (phase II is a non-halogen fiame retardant, it acts a fiame retardant by intumescence mechanism. When APP II is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia, The polyphosphoric acid reacts reacts with hydroxy 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.
Active and passive fire protection
Fire protection of steel can be done with two methods:
Active fire protection
● Methods that require a certain amount of motion and
response in order to react to put out the fre
● E.g. sprinkler systems, fire extinguisher systems
Passive fire protection
● Methods that contain, minimize the impact, or slow the
spread of the fire
● Contrary to active fire protection, the passive type does
not need a response before reacting to the fire
● E.g. intumescent coatings, boards, fire walls, foams
