Model No.: CF-APP202

Melamine modified APP-II(CF-APP202) is a flame retardant based on phosphorus/nitrogen synergism, free formaldehyde,manufactured from CF-APP201 with melamine modified according to own method.
CF-APP202 is differs from CF-APP201 in the following properties:

-Reduce water solubility;
-Reduce viscosity in water;
-Obviously improve dispersibility and compatibility with plastic materials;

-Increase fluidity of powder;

-Improve thermal expansion efficiency during inflaming retarding process.
