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.

Applications:
CF-APP203 can be used for all applications that CF-APP201 is suitable. CF-APP203 has lower solubility in water and viscosity.These features make CF-APP203 is suitable for water-fast intumescent system in polymers(PU, PU,PBT,etc.) and paints.
Use:
-Fiber materials( paper, wood, fireproof textile);
-All kinds of polymers ( sunproof, waterproof, or fireproof outdoor materials);
-Fire-refractory building board, coiled material;
-Epoxy resin and unsaturated resin;
-Cable and rubber;
-Plastic material of electron device;
-Textile
Packing : 25kg woven bag with plastic liner. |
