Abstract

Herstellungsverfahren zur Herstellung sehr dünner monolithischer Schichten aus thermoplastischem Polyurethan (TPU), wobei eine extrudierte Schicht von TPU (7) mittels eines Extrusionsbeschichters auf eine Substratschicht (8) geschmolzen wird, dadurch gekennzeichnet, dass das geschmolzene Polymer als relativ dicker Film aus dem Extrusionskopf (1) fließt und, in dem Abstand von dem Extruderkopf zum Walzenspalt, auf die sehr dünne Dicke von 8 bis 100 Mikrometer, bevorzugt von 30 bis 60 Mikrometer, gedehnt wird und danach durch eine Druckwalze (9), die durch eine andere Walze (10) unterstützt wird, auf ein durch eine Führungswalze (12) getragenes Substrat (8) geschmolzen wird, an einer Seite der geschmolzenen Polymerschicht (7), wobei eine Kühlwalze (11) Gegendruck ausübt und den geschmolzenen Film kühlt und härtet, wonach das Fertigprodukt (14), getragen durch eine andere Führungswalze (13), den Herstellungsvorgang verlässt.
