Beschreibung
Zusammenfassung:	The disclosed technology relates to an article, such as a hose, tube, sheet, film, or filament made from a crystalline thermoplastic polyurethane composition, wherein the crystalline thermoplastic polyurethane composition comprises the reaction product of a polyisocyanate component, a polyester polyol component, optionally a chain ex- tender component, and optionally a catalyst. The article is produced by melt or extrusion processes. La présente invention concerne un article tel qu'un tuyau, un tube, une feuille, un film ou un filament fabriqué à partir d'une composition de polyuréthane thermoplastique cristallin, ladite composition de polyuréthane thermoplastique cristallin comprenant le produit de réaction d'un composant polyisocyanate, d'un composant polyol de polyester et, éventuellement, d'un composant de chaîne ex-tendre et, éventuellement, d'un catalyseur. L'article est produit par fusion ou par extrusion.
