Abstract

A multilayer flexible tube includes an inner layer including a melt processable fluoropolymer, wherein the fluoropolymer includes a copolymer of a poly vinylidene fluoride (PVDF) and a hexafluoropropylene (HFP); and an outer layer including a melt processable polymer having a shore hardness less than a shore hardness of the inner layer, wherein the multilayer flexible tube has a maximum storage modulus of at least 300 MegaPascal (MPa) at a temperature of about −10° C.
