Title
(EN) POLYTETRAFLUOROETHYLENE LAMINATE AND METHOD OF PRODUCING SAME
(FR) LAMINE DE POLYTETRAFLUOROETHYLENE ET PROCEDE DE PRODUCTION
Abstract
(EN)
A flexible fluoroplastic laminate comprising a plurality of unsintered oriented PTFE films laminated under conditions of elevated temperature and pressure. At least one of the films has its direction of orientation disposed angularly with respect to that of at least one other of the films. The films retain their orientation following lamination.
(FR)
Un laminé de matière fluoroplastique souple comprend plusieurs couches de PTFE (polytétrafluoroéthylène) non frittées et orientées, laminées dans des conditions de température et de pression élevées. Une de ces couches au moins est orientée de manière à faire un angle par rapport à l'orientation d'au moins une autre couche. Ces couches gardent leur orientation après lamination.
