Molecular Formula: (NH4PO3)n n>1000
Model No.: JD-657
Crystal form phase II ammonium polyphosphate (JD-657) is a nitrogen-containing halogen-free environment-friendly flame retardant, especially for the use of anti-fire retardant coating .The product has high degree of polymerization, good thermal stability, low hygroscopicity. Unlike halogen-containing flame retardant, in the burning process it forms expanded carbon layer to insulate heat and air. JD-515 has low smoke, low toxicity, no droplets, is a highly efficient inorganic environment-friendly flame retardant.
