Ammonium Polyphosphate CAS-No.: 68333-79-9
Ammonium polyphosphate is a white free flowing powder. It is a non-halogenated additive flame retardant。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).
