Title (EN) ELECTRET ARTICLE HAVING HIGH FLUOROSATURATION RATIO
(FR) ARTICLE ELECTRET AYANT UN TAUX ELEVE DE FLUOROSATURATION
Abstract: front page image
(EN)An electret article that includes a polymeric material that has electric charge imparted thereto, that has a CF3:CF2 ratio of at least 0.15 and that has a fluorosaturation ratio greater than about 200. The electret article may be in the form of a porous web of polymeric fibers suitable for use as a filter. The inventive electret article is resistant to charge degradation upon exposure to high temperatures for prolonged time periods.
(FR)L'invention porte sur un article électret comprenant un matériau polymère auquel est imputée une charge électrique et qui a un rapport CF3#191:CF2#191 d'au moins 0,15 et un taux de fluorosaturation supérieur à environ 200. L'article électret peut se présenter sous la forme d'une bande poreuse de fibres polymères appropriée pour être utilisée comme filtre. L'article électret de l'invention résiste à la dégradation de la charge lors d'une exposition à de hautes températures sur des durées prolongées.
