Process for producing foam plates with high pressure resistance.
摘要
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
