Abstract
(DE)
Der Kombinationsschaum enthält eine Matrix aus Polyurethanschaum mit darin enthaltenen geschäumten Partikeln aus thermoplastischem Polyurethan, wobei Matrix und Partikel jeweils aus Polyol-Komponenten und Polyisocyanat-Komponenten aufgebaut sind, wobei mindestens 0 Gew.-% der die Polyol-Komponenten der Matrix und Partikel bildenden Grundbausteine identisch sind und mindestens 50 Gew.-% der die Polyisocyanat-Komponente der Matrix und Partikel bildenden Grundbausteine identisch sind.
(EN)
The invention relates to a combination foam containing a matrix of polyurethane foam having foamed particles of thermoplastic polyurethane contained in the matrix, wherein the matrix and the particles are each composed of polyol components and polyisocyanate components, wherein at least 0 wt% of the fundamental units forming the polyol components of the matrix and particles are identical and at least 50 wt% of the fundamental units forming the polyisocyanate components of the matrix and particles are identical.
(FR)
L'invention concerne une mousse combinée contenant une matrice en mousse de polyuréthane dans laquelle sont incluses des particules expansées de polyuréthane thermoplastique. La matrice et les particules sont constituées chacune d'un composant polyol et d'un composant polyisocyanate. Au moins 50 % en poids des motifs formant le composant polyol de la matrice et des particules sont identiques et au moins 50 % en poids des motifs formant le composant polyisocyanate de la matrice et des particules sont identiques.
