Title (EN) FUEL TUBINGS AND METHODS FOR MAKING AND USING SAME
(FR) TUBES À CARBURANTS ET LEURS PROCÉDÉS DE FABRICATION ET D'UTILISATION
Abstract:
(EN) The present disclosure relates to multi-layered tubings that are fuel resistant and resistant to delamination. In one aspect, the disclosure provides a length of tubing having an annular cross-section including an annular fluoropolymer layer formed from at least 75 wt% fluoropolymer (e.g., at least 75 wt% of a PVDF polymer), the fluoropolymer layer having an outer surface and an inner surface; and disposed about the fluoropolymer layer, an annular thermoplastic layer formed from at least 75 wt% thermoplastic (e.g., thermoplastic polyurethane, thermoplastic polyamide and/or thermoplastic polyester), the thermoplastic polyurethane layer having an inner surface in contact with the outer surface of the fluoropolymer layer and an outer surface, wherein the fluoropolymer layer is covalently bound to the thermoplastic polyurethane layer, for example, by electron beam treatment.
(FR) La présente divulgation concerne des tubes multicouches doués de résistance aux carburants et de résistance au délaminage. Selon un aspect, la présente divulgation concerne une longueur de tube ayant une section transversale annulaire constituée d'une couche de polymère fluoré annulaire formée à partir d'au moins 75 % en poids de polymère fluoré (p. ex., au moins 75 % en poids d'un polymère de PVDF), où la couche de polymère fluoré a une surface extérieure et une surface intérieure ; et agencée autour de la couche de polymère fluoré, une couche thermoplastique annulaire formée à partir d'au moins 75 % en poids de thermoplastique (p. ex., polyuréthane thermoplastique, polyamide thermoplastique et/ou polyester thermoplastique), où la couche de polyuréthane thermoplastique a une surface intérieure en contact avec la surface extérieure de la couche de polymère fluoré et une surface extérieure, et la couche de polymère fluoré est liée par covalence à la couche de polyuréthane thermoplastique, par exemple, par traitement par faisceau d'électrons.
