Exolit AP 750 Ammonium Polyphosphate Clariant Flame and Smoke Retardants >> Phosphorus based Ethylene co-terpolymers - solid (EVA, EMA...) Polyolefins (PE, PP…) ADHESIVE >> Hot-melt Exolit AP 750 Ammonium Polyphosphate Exolit AP 750 is a non-halogenated flame retardant based on Exolit AP 422, which develops its effectiveness through phosphorus / nitrogen synergism. When incorporated into thermoplastics, it shows high processing stability. Exolit AP 750 differs in its mode of action from chlorine- or bromine-containing flame retardants by achieving its effect through intumescence. The thermoplastic material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect, reduces further oxygen access and prevents dripping of the thermoplastic. Exolit AP 750 may be used in a range of thermoplastics, especially polypropylene, polyethylene, ethylene/vinyl acetate copolymers and polyolefin blends. It is suitable both for extrusion and injection moulding applications. In addition Exolit AP 750 is suitable for use in hot melt adhesives, in epoxy gelcoats or coating compounds. Ammonium polyphosphate. Used as a non-halogenated flame retardant in hot melt adhesives. Offers high processing stability.
