Title (EN) FLEXIBLE PIPES MADE OF A POLYARYLETHERKETONE / PERFLUOROPOLYMER COMPOSITION
(FR) TUYAUX FLEXIBLES CONSTITUÉS D'UNE COMPOSITION DE POLY(ARYL-ÉTHER-CÉTONE)/POLYMÈRE PERFLUORÉ
Abstract: front page image
(EN)Flexible pipe (fP) suitable for transporting hydrocarbons, said flexible pipe comprising at least one polymer layer (L) composed of a polymer composition (C) comprising at least one poly(aryl ether ketone) (P1), and at least one per(halo)fluoropolymer (P2). The poly(aryl ether ketone) (P1) and the per(halo)fluoropolymer (P2) are advantageously homogeneously distributed in the polymer composition (C). The polymer composition (C) is profitably prepared by a method comprising tumble blending the per(halo)fluoropolymer (P2) on one hand, and the poly(aryl ether ketone) (P1) or part of the poly(aryl ether ketone) (P1) on the other hand.
(FR)L'invention porte sur un tuyau flexible (fp) approprié pour le transport d'hydrocarbures, ledit tuyau flexible comprenant au moins une couche de polymère (L) composée d'une composition de polymère (C) comprenant au moins une poly (aryl-éther-cétone) (P1) et au moins un polymère per(halo)fluoré (P2). La poly (aryl-éther-cétone) (P1) et le polymère per(halo)fluoré (P2) sont avantageusement répartis de façon homogène dans la composition de polymère (C). La composition de polymère (C) est de manière rentable préparée par un procédé comprenant le mélange par culbutage du polymère per (halo)fluoré (P2) d'un côté et de la poly(aryl-éther-cétone) (P1) ou d'une partie de la poly(aryl-éther-cétone) (P1) d'un autre côté.
