Abstract: Foamable olefine polymer particles are coated with a thermoplastic whose softening temp is below that of the polymer. No adhesives are used. The granules of foam polymer are coated with thermoplastic film by using suitable dispersion, solutions or powder. Aqueous dispersions are pref. and dispersions based on a polyacrylic acid ester are found suitable. The coated granules are heated to a temp. below the softening temp. of the foamed polymer but above that of the coating material. Coated granules are pressed in a hermetical vessel to a reduced volume and the composite material moulding is cooled under pressure.
