Ammonium Polyphosphate Cas No. 68333-79-9
Ammonium polyphosphate is a halogen-free additive flame retardant , white free flowing powder.
Ammonium polyphosphate is particularly suitable as an ”acid donor” for intumescent coatings. Other essential components of intumescent systems include a binder, a carbon donor (e.g. pentaerythritol) and a blowing agent (e.g. melamine).
