Exolit® AP 740 is a white free flowing powder. It is a non-halogenated additive flame retardant based on ammonium polyphosphate which develops its effectiveness through phosphorus/nitrogen synergism. Exolit® AP 740 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.
