Abstract
Abstract Translated from German Der Hartschaumstoff, insbesondere der weitgehend geschlossenzellige Polyurethan- oder Polyisocyanurat-Schaumstoff, hat eine im wesentlichen homogene Zellstruktur mit einer Zellengröße von bevorzugt als 100 µm Durchmesser und mit im wesentlichen CO₂-Treibgas als Zelleninhalt. The rigid foam, in particular the largely closed-cell polyurethane or polyisocyanurate foam, has an essentially homogeneous cell structure with a cell size of preferably 100 μm in diameter and with essentially CO₂ propellant gas as the cell content.
