Product discription:

Exflam202 is a flame retardant based on phosphorus /nitrogen synergism.manufactured from Exflam201 with melamine resin react coated according to our own method.

Exflam202 is differs from Exflam201 in the following properties:
　　marked reduction in water soluble constituent.
　　marked reduction viscosity in aqueous suspension
　　marked enhance wetting out and compatibility with polymers or resin
　　improved powder flowability
　　improved heat resistance and against electric-arc

Application:

Exflam202 can be used for all Exflam201 is suitable

Exflam202 can　be used advantageously in intumescent coating for exterior application where the ammonium polyphosphate is required to have extremely low water solubility

Exflam can be used in cellulose-containing materials (paper, wood, car’s fireproof cloth, military cellulose materials）.

Exflam202 can be used in various polymers for exterior application.

Safety and Toxicity:

Exflam202 is innocuous, which is advisable to store in a hidden dry place.
Safety step should be acted owing to fine powder

Package:

25kg paper bag or on customer’s request.
