Exolit® IFR 36

Ammonium polyphosphate flame retardant system for thermosets, especially epoxy resins

Edition Date :
May 28, 2014
Exolit IFR 36 is a non-halogenated flame retardant based on ammonium polyphosphate, which develops its effectiveness through phosphorus/nitrogen synergism. Exolit IFR 36 differs in its mode of action from chlorine- or bromine-containing flame retardants by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat insulating effect and reduces further oxygen access.

Benefits
  • Non-halogenated flame retardant based on ammonium polyphosphate which develops its effectiveness through phosphorus/nitrogen synergism
  • Differs in its mode of action from chlorine- or bromine-containing flame retardants by achieving its effect through intumescence
  • May be used in a range of thermosets, especially epoxy resins
  • Suitable both for coatings and reinforced materials
  • In composites, it may be used alone or in combination with aluminium trihydroxide (ATH)
  • Non-halogenated flame retardant with favorable environmental and health profile
