Abstract: A multilayer flexible tube includes an inner layer including a melt processable fluoropolymer, wherein the melt processable fluoropolymer includes a terpolymer including a tetrafluoroethylene, a hexafluoropropylene, and a vinylidene fluoride (THV); a tie layer including a polymeric blend of a terpolymer including a tetrafluoroethylene, a hexafluoropropylene, and a vinylidene fluoride (THV) with a poly vinylidene fluoride (PVDF), a polyamide, a polyetheramide block copolymer, or combination thereof; and an outer layer including a melt processable polymer having a shore hardness less than a shore hardness of the inner layer.

Abstract: 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.
