Title
(EN) HIGH TEMPERATURE, CHEMICAL RESISTANT FILTRATION LAMINATE
(FR) STRATIFIE HAUTE TEMPERATURE, RESISTANT AUX ATTAQUES CHIMIQUES ET DESTINE A DES SYSTEMES DE FILTRATION
Abstract
(EN)
A self-supporting laminate (20) formed from an expanded polytetrafluoroethylene membrane material (11) and a coated metal mesh material (10) is described that is self-supporting and can be formed into a pleated filter member (30).
(FR)
On décrit un stratifié (20) rigide formé à partir d'un matériau (11) membranaire en polytétrafluoroéthylène et d'un maillage (10) métallique enrobé, apte à se tenir droit de façon autonome, et pouvant être mis sous la forme d'un élément (30) de filtre plissé.
