Abstract: The invention relates to a method of producing foam slabs having a density of 20 to 20 to 200 g.l and a cross-section of at least 50 cm by extrusion and foaming a mixture from a styrene polymer, 3 to 15 % by weight of a foaming agent mixture and preferably 0.01 to 10 % by weight of graphite particles, each based on the styrene polymer. The foaming agent is a mixture of 79 to 28 % by weight of CO2; 50 to 10 % by weight of ethanol; 11 to 22 % by weight of a saturated or unsaturated, aliphatic C3-C5 hydrocarbon, preferably isobutane, and 0 to 20 % by weight of water.

Abstract: The invention relates to a method of producing foamed slabs with a density of 20 to 200 g.1 and a cross-section of at least 50 cm . The inventive foamed slabs are produced by extruding and foaming a mixture from a styrene polymer, 3 to 15 percent by weight of a volatile foaming agent and 0.2 to 10 percent by weight graphite particles, each based on the styrene polymer, and optionally conventional additives. The invention is also characterized in that the volatile foaming agent is a mixture from 95 to 20 percent by weight CO2, 5 to 90 percent by weight H2O and 0 to 75 percent by weight of a volatile organic compound.

Abstract: Extruded foam slabs based on styrene polymer, with an open cell content of more than 80%, in which the thermoplastic matrix contains (A) 90-50 wt% styrene polymer and (B) 10-50 wt% polymethyl methacrylate. An Independent claim is also included for a process for the production of these foam slabs by extrusion of a thermoplastic melt containing (A), (B) and optionally a thermoplastic (C) with a glass transition point (Tg) above 140 deg C, together with 1-15 wt% volatile blowing agent (based on A + B + C) and optionally other additives, at 110-150 deg C.
