Ammonium Polyphosphate Cas No. 68333-79-9
APP50(PHASE I) is one type of Ammonium polyphosphate ,it is a white powder. belong to 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).
