Abstract

L'invention concerne un pansement en couches, utilisé en tant que pansement pour plaies, comprenant une couche de mousse (10) et une couche de couverture (20), la couche de couverture (20) contenant un polymère thermoplastique, de préférence du polyuréthane, et cette couche est au moins partiellement reliée directement à la couche de mousse (10). La couche de mousse (10) comprend une mousse de polyuréthane, obtenue par moussage puis séchage d'une composition comprenant une dispersion de polyuréthane (I) aqueuse et hydrophile à l'état anionique. La mousse peut être stabilisée avec des blocs d'oxyde d'éthylène/ oxyde propylène copolymères. L'invention concerne également un procédé de production dudit pansement en couches ainsi que son utilisation en tant que pansement pour plaies, par exemple.
