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



APP Phase II has an high polymerization degree, with n>1000, its structure is cross linked (branched), and it is an high-quality non-halogenated flame retardant. APP phase II, Ammonium polyphosphate, has an higher thermal stability (the decomposition starts at approximately 275°C) and lower water solubility than APP I.


Main Applications:
Solvent based and Water based intumescent coatings.
Flame retardant for polyurethanes.
Flame retardant for unsaturated polyesters.
Flame retardant for epoxies.
Flame retardant for acrylics.


How does flame retardant work?

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.
