Description :
Ammonium polyphosphate (Phase II) is a non-halogen flame retardant. It acts as flame 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 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.
Charateristics:
1. Halogen-free and environmentally friendly flame retardant
2. Low water solubility, extremely low aqueous solution viscosity, low acid value
3. Good thermal stability, migration resistance and precipitation resistance
4. The particle size is extremely small, especially suitable for occasions with high particle size requirements, such as high-end fireproof coatings, textiles
Coating, polyurethane rigid foam, sealant, etc.;
5. Biodegradable into phosphorus and nitrogen compounds
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
