Abstract: Foam panels having a high compressive strength are produced by extrusion of a mixture of a styrene polymer and 5 to 16% by weight of a blowing agent mixture which contains… a) 3 to 70% by weight of an alcohol or ketone having a boiling point between 56 and 100 DEG C,… b) 5 to 50% by weight of carbon dioxide and… c) 0 to 90% by weight of a saturated C3- to C5-hydrocarbon and/or of a hydrogen-containing chlorofluorocarbon or fluorocarbon boiling between -30 DEG and +30 DEG C.

Abstract: Foams of high compressive strength are obtained by extruding a mixture of a styrene polymer and from 3 to 9 % by weight of a blowing agent comprising from 80 to 100 % by weight of CO2 and from 0 to 20 % by weight of at least one hydrocarbon or halogenated hydrocarbon which is gaseous at room temperature, the mixture being extruded in a zone at an excess pressure of from 0.1 to 2 bar, and the foam being allowed to solidify under this pressure.

Abstract: A process is disclosed for manufacturing slabs of cellular material having at least 20 mm thickness and at least 50 cm cross-section by extrusion of a mixture of a styrene polymer and 1 to 10% by weight of a foaming agent, in relation to the styrene polymer. The process is characterized in that the foaming agent contains at least one ether from the group of the dimethyl, methylethyl and methylvinyl ethers.

Abstract: Foams with high compressive strength (I) are mfd. by extruding a mixt. of a styrene polymer (II), 3-9 wt.% blowing agent (III) comprising 80-100 wt.% CO2 and 0-20 wt.% hydrocarbon or halogenated hydrocarbon which is a gas at room temp. (IV), and the usual additives if required; the mixt. is extruded in a zone with an overpressure of 0.1-2 bar and allowed to set at this pressure. Pref. component (IV) has b.pt. -50 to +15 deg.C. (IV) is, e.g. propane, butane, isobutane, MeCl, EtCl, CCl2F2, etc.; pref., overpressure in the extrusion chamber is 0.4-1.6 bar.
