Abstract: Foam sheets of 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) from 3 to 70% by weight of an alcohol or ketone having a boiling point of between 56 and 100 DEG C b) from 0 to 50% by weight of carbon dioxide, c) from 0 to 88% by weight of a saturated C3- to C5-hydrocarbon, and d) from 2 to 90% by weight of at least one fluorinated hydrocarbon which boils at between -30 DEG and +30 DEG C. p

Abstract: Production Of Fine-Celled Foams From Sytrene Polymers of the Invention Fine-celled foams are produced by a process in which a styrene polymer is melted, the melt is mixed with a volatile blowing agent and a nucleating agent under superatmospheric pressure, the mixture is let down to atmospheric pressure, and the foam is cooled. The nucleating agent employed comprises from 0.02 to 2% by weight of the calcium salt of a long-chain fatty acid, and from 0.01 to 1% by weight of a finely divided, inorganic substance which is insoluble in the styrene polymer, a mixture of calcium stearate and magnesium oxide being preferred.
