Product description:
Silane modified APP-II(CF-APP203) is a flame retardant based on phosphorus /nitrogen synergism, it is treated by Silane based on CF-APP201 with special method.CF-APP203 is different from CF-APP201 in such features as bellow:
-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.
