Title (EN) THERMOPLASTIC POLYURETHANE MATERIALS FOR FORMING MEDICAL DEVICES
(FR) MATÉRIAUX DE POLYURÉTHANNE THERMOPLASTIQUES POUR FORMER DES DISPOSITIFS MÉDICAUX
Abstract: front page image
(EN)Principles and embodiments of the present invention relate generally to thermoplastic polyurethane materials having controlled and improved stiffness and/or flexibility, and methods to prepare them. The thermoplastic polyurethanes described herein having superior stiffness and softening properties may be fabricated into film, tubing, and other forms of medical devices. The thermoplastic polyurethanes comprise: an aromatic diisocyanate excluding non-aromatic diisocyanates; at least one polyglycol; and a chain extender comprising at least one side-chain branching diol and excluding linear diols.
(FR)De manière générale, les principes et les modes de réalisation selon la présente invention concernent des matériaux de polyuréthanne thermoplastiques ayant une rigidité et/ou flexibilité améliorées et contrôlées, et des procédés pour les préparer. Les polyuréthannes thermoplastiques ci-décrits ayant des propriétés de rigidité et de ramollissement supérieures peuvent être convertis en films, tubulures, et autres formes de dispositifs médicaux. Les polyuréthannes thermoplastiques comprennent : un diisocyanate aromatique excluant les diisocyanates non aromatiques; au moins un polyglycol; et un allongeur de chaîne comprenant au moins un diol à ramifications latérales et excluant les diols linéaires.
