falme hemmende Ammoniumpolyphosphat Faser oder pa

1. Brief Introduction: Ammonium polyphosphate(APP) molecular formula(NH4PO3)n, n>50, water-solubility less than 2g/100ml. As inorganic chain polymer, there’s P-N collaboration effect because of high phosphorus and nitrogen content, so it has excellent fire retardant effect. It can be used in architecture, shipping, cable field and so on. Used as an essential fireproofing additive in expansive fireretardant coating and fire retardants. 2.
