Title (EN) BREATHABLE FILM
(FR) FILMS PERMEABLES A L'AIR
Abstract:
(EN) A thermoplastic composition containing a mixture of (a) a block copolyether ester, a block copolyether amide and/or a polyurethane; (b) a thermoplastic homo-, co- or terpolymer that is incompatible with (a); and (c) a compatibilizer; and its use in preparing films is disclosed. Such films demonstrate moisture vapor permeability, while acting as barriers to liquids and microorganisms.
(FR) L'invention concerne une composition thermoplastique consistant en un mélange de (a) un copolyéther ester bloc, un copolyéther amide bloc et/ou un polyuréthane; (b) un homo-, co- ou terpolymère thermoplastique incompatible avec (a); et un compatibiliseur, ainsi que son utilisation dans la préparation de films. De tels films s'avèrent perméables à la vapeur d'eau tout en formant des barrières vis à vis des liquides et des micro-organismes.
