ammonium polyphosphate halogen-free flame retardant


Ammonium polyphosphate
(phase-II) treated by melamine
Molecular formula :(NH4PO3)n  n>1000
CAS No.: 68333-79-9    
HS CODE: 2835.3990
Model No.: FR231


Product description:
Melamine modified APP-II is a flame retardant based on phosphorus /nitrogen synergism, free formaldehyde, manufactured from APP II with melamine modified according to own method.
FR231 is different from FR201 in the following properties:
-Reduce solubility in water;
-Reduce viscosity in water;
-Obviously improve dispersibility and compatibility with polymers and resins;
-Increase fluidity of powder;
-Improve thermal expansion efficiency during inflaming retarding process and insulation performance.
