PRODUCT OVERVIEW

DESCRIPTION

Ammonium Polyphosphate APP II (various grades) is a non-halogen flame retardant that operates through an intumescence mechanism. When exposed to heat or fire, it decomposes into ammonia and polymeric phosphate acid, forming a protective barrier. Known for its higher thermal stability and lower water solubility compared to APP I, APP II is a white powder that is non-hazardous and can be shipped as a regular product. It is widely used in applications requiring effective fire resistance without the environmental concerns associated with halogenated compounds.
