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).

Properties

Ammonium polyphosphate, also known as ammonium polyphosphate (APP), is non-toxic and tasteless, does not produce corrosive gas and has high thermal stability. It is a non halogen flame retardant with excellent performance; However, it also has its own shortcomings that are difficult to overcome, such as poor compatibility with polymers and poor dialysis resistance. Once the polymer surface is precipitated, it is easy to absorb moisture and water-soluble and hydrolyze in a humid environment, which affects the weather resistance and electrical properties of polymers and limits its application range.
