Product Desciption
Polyphosphoric acids , Ammonium salts
1. Application
Ammonium Polyphosphate (APP), Cas No 68333-79-9, is an environment-friendly and halogen-free flame retardant. APP is the main constituent of many intumescent flame retardant systems: coatings, paints and engineering plastics.
For the chemical point of view, Ammonium Polyphosphate is an inorganic salt of polyphosphoric acid and ammonia. Depending on the polymerization degree, there are two main families of ammonium polyphosphate: Crystal phase I APP (or APP I), and Crystal phase II APP (or APP II).
- APP phase I has a short and linear chain (n < 100), it is more water sensitive (hydrolysis) and less thermally stable; actually it begins to decompose at temperatures above 150 °C.
- The second family of Ammonium polyphosphate is the APP Phase II; which 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 300°C) and lower water solubility than APP I.
APP phase II is probably one of the most effective non-halogen fire retardants in the market.
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.
