Exolit® IFR 36

Ammonium polyphosphate flame retardant system for thermosets, especially epoxy resins

Edition Date :
April 20, 2022
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 aluminum trihydroxide (ATH)
  • Non-halogenated flame retardant with favorable environmental and health profile

Applications

Exolit IFR 36 may be used in a range of thermosets, especially epoxy resins. It is suitable both for coating and reinforced materials.

Intumescent Coatings
Exolit IFR 36 offers a unique performance when incorporated into epoxy-based intumescent coatings. It is especially suitable for passing standards for the steel protection of hydrocarbon fire scenarios.

Composite Applications
In composites Exolit IFR 36 may be used alone or in combination with aluminum trihydrate (ATH).
In composites for transport applications it can be used to control fire, smoke and toxicity. Especially in railway (EN 45545-2) and aviation (FAR 25.853) applications low smoke density and toxicity is a key requirement. Moreover Exolit IFR 36 can be used to control heat release in epoxy composites for aviation.

Packaging and Handling
