Summary: | The invention relates to compositions and methods for solid freeform fabrication of medical devices, components and applications in which the composition includes a thermoplastic polyurethane which is particularly suited for such processing. The useful thermoplastic polyurethanes are derived from a polyisocyanate component including a first linear aliphatic diisocyate and a second aliphatic diisocyanate, a polyol component, and (c) a chain extender component.
L'invention concerne des compositions et des procédés pour la fabrication en formes irrégulières solides de dispositifs médicaux, des composants et des applications, la composition comprenant un polyuréthane thermoplastique qui est particulièrement approprié à ce type de traitement. Les polyuréthannes thermoplastiques utilisés sont dérivés d'un composant polyisocyanate comprenant un premier diisocyate aliphatique linéaire et un second diisocyanate aliphatique, un composant polyol, et (c) un composant allongeur de chaîne. |
