Title (EN) FLUOROPOLYMER GAS SEPARATION FILMS
(FR) FILMS DE POLYMÈRES FLUORÉS POUR SÉPARER LES GAZ
Abstract: front page image
(EN)The invention relates to a novel film, membrane or powder media made from fluoropolymers, especially PVDF-based and ETFE-based polymers, which are suitable for separating gases, especially carbon dioxide, from a gas mixture. The novel film has good selectivity, high permeance, good mechanical properties, and exhibits a high resistance to oxidant and acid attack. The separation film is especially useful in harsh and corrosive environments.
(FR)La présente invention concerne un film, une membrane ou une poudre préparés à partir de polymères fluorés, en particulier des polymères à base de PVDF et d'ETFE, appropriés pour séparer les gaz, en particulier le dioxyde de carbone, d'un mélange gazeux. Le nouveau film est très sélectif et très perméable, possède de bonnes propriétés mécaniques et présente une résistance élevée contre les attaques par les oxydants et les acides. Le film de séparation est particulièrement utile dans les environnements corrosifs.
