Title (EN) MICROPOROUS POLYETHYLENE FILM THROUGH LIQUID-LIQUID PHASE SEPARATION MECHANISM AND PREPARING METHOD THEREOF
(FR) FILM DE POLYETHYLENE MICROPOREUX OBTENU PAR UN MECANISME DE SEPARATION EN PHASE LIQUIDE-LIQUIDE ET PROCEDE POUR LE FABRIQUER
Abstract: front page image
(EN)Disclosed in the present invention are a microporous polyethylene film and a method of manufacture thereof. The polyethylene microporous film manufactured according to the present invention may contribute to an increased productivity of stable products as its extrusion and stretching may be done readily. And thus manufactured product may be used for battery separators and various filters owing to its high gas permeability, superior puncture strength, and small ratio of shrinkage.
(FR)La présente invention décrit un film de polyéthylène microporeux et un procédé pour le fabriquer. Le film de polyéthylène microporeux fabriqué conformément à l’invention peut favoriser une productivité plus élevée de produits stables car il se prête facilement à l’extrusion et à l’étirage. Un produit ainsi fabriqué peut servir à des séparateurs de batterie et divers filtres grâce à sa perméabilité élevée aux gaz, à sa résistance élevée à la perforation et à son faible rapport d’étirage.
