Title (EN) EXTRUDING THIN MULTIPHASE POLYMER FILMS
(FR) EXTRUSION DE FILMS DE POLYMERES MINCES A PLUSIEURS PHASES
Abstract: front page image
(EN)Methods of extruding thin multiphase polymer films using a flat film extrusion die closely spaced to a nip to transport and cool the melt from the die to produce thin multiphase polymer films having substantially uniform calipers of about 250 micrometers or less.
(FR)L'invention concerne des procédés d'extrusion de films de polymères minces à plusieurs phases à l'aide d'une matrice à extrusion de films située à proximité d'un rouleau pinceur. Il est ainsi possible de transporter et de refroidir le produit en fusion, à partir de la matrice pour produire des films de polymères minces à plusieurs phases, dont l'épaisseur est sensiblement uniforme, à savoir, d'environ 250 micromètres ou moins.
