Ammonium polyphosphate
name：Ammonium polyphosphate
Formula：
M.W：
CAS NO.：
Characters：White liquid powder.GD - APP102 melamine coated ammonium polyphosphate in GD - APP101 ammonium polyphosphate by melamine surface modification, the product has the basic function of the latter, another GD - APP102 differs from that of GD - APP101 advantages are: reduce the solubility in water;Significantly reduce the viscosity in water;The dispersibility and compatibility of flame retardant plastic base materials are significantly improved.Increased the fluidity of the powder;The thermal expansion efficiency of flame retardant process is improved.
Usage：Expansive fire retardant coating (acid and solvent);Fireproof construction sheet material;Thermoplastic polyolefin and unsaturated aromatic hydrocarbon plastics;Polyurethane foam;Epoxy and unsaturated resins;Cables and rubber;Electronic components plastic material;Fabric.
