Product description:
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 different from CF-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.
