The aim of the study is to investigate new intumescent materialsbased on ethylene‐vinyl acetate copolymers. Hostaflam AP 750is used as a flame‐retardant system. Fire testing and thermalanalyses have shown that the incorporation of AP 750 leads to theformation of an intumescent coating which provides good fire barrierproperties. Spectrochemical analyses have shown that the coatingconsists of polyethylenic chains issued from the polymer.Polyaromatic structures and phosphorus oxides are also observed inthe coating. © 1999 Society of Chemical Industry
