Abstract

Die vorliegende Erfindung betrifft einen Schichtenverbund, geeignet als Wundauflage, umfassend eine Schaumschicht (10) sowie eine Deckschicht (20), wobei die Deckschicht (20) thermoplastisches Polymer, vorzugsweise Polyurethan, umfasst und zumindest teilweise direkt mit der Schaumschicht (10) verbunden ist und wobei die Schaumschicht (10) einen Polyurethanschaum umfasst, der erhalten wird, indem eine Zusammensetzung umfassend eine wässrige, anionisch hydrophilierte Polyurethandispersion (I) aufgeschäumt und getrocknet wird. Der Schaum kann mit Ethylenoxid/Propylenoxid-Blockcopolymeren stabilisiert werden. Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung eines solchen Schichtenverbundes sowie dessen Verwendung beispielsweise als Wundauflage.
