Abstract

An expandable styrene polymer (I) compsn. contains volatile blowing agent (II), non-waxy halogenated flame retardant (III) and 0.03-2 wt.% of a wax (IV) melting above the foaming pt. of the polymer (I) but below 140 deg.C. In forming an extruded (I) foam by expressing a heat plastified (I) gel contg. volatile fluid foaming agent and (III) from a die into a region of reduced press. to form a cellular foam and cooling to a temp. at which the foam is self-supporting, the improvement comprises incorporating into the heat plastified unfoamed gel, 0.03-2 wt.% (based on (I)) of the wax (IV). - Incorporation of (IV) imparts improved flammability props. without significantly increasing the cell size of the foam.
