Title (EN) A POLYURETHANE WITH DELAYED RELAXATION BEHAVIOUR FOR COMPRESSION PRODUCTS
(FR) POLYURÉTHANE PRÉSENTANT UN COMPORTEMENT DE RELAXATION RETARDÉ POUR PRODUITS DE CONTENTION
Abstract:
(EN) The invention relates to medical aids, in particular compression products, such as compression stockings or bandages. More specifically, the invention relates to compression products comprising fibre forming polyurethane polymers showing a delayed continuous relaxation behaviour. The invention furthermore relates to polyurethane polymers containing N-diol and corresponding quaternised polyurethane polymers, to a process of producing the polyurethane polymers, to blends with elastane, as well as to uses.
(FR) L'invention concerne des aides médicales, en particulier des produits de contention, tels que des bas de contention ou des bandages. Plus spécifiquement, l'invention concerne des produits de contention comprenant des polymères de polyuréthane fibrogènes présentant un comportement de relaxation continu retardé. L'invention concerne en outre des polymères de polyuréthane contenant un N-diol et des polymères de polyuréthane quaternisé correspondants, un procédé de production des polymères de polyuréthane, des mélanges avec de l'élasthanne, ainsi que des utilisations.
