chemical auxiliary agent- app phase II

1. No toxicity,No halogen 2. High degree of polymerization 3.High compatibility 4.Quality products with low prices (HC-APP)

Molecular formula : (NH4PO3)n   n>1000Model No.: HC-APP

Crystallized II type Ammonium Polyphosphate is a kind of environmental-protected and no-halogen flame retardant with Nitrogen structure. With the characteristic of high degree polymerization, good heat stability and low moisture absorption. It is different to halogen flame retardant, the inflation carbon layer of APP can reach to heat insulation, isolate atmosphere flam retardant effect. APP have also low smoke, no toxicity, no molten drop, is a high effection and inorganic new type flame retardant material.
