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.
TF-APP231 is different from TF-APP201 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.
