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.

Abstract: Systems and methods are disclosed that include providing a multilayer tubing construction with an inner layer, an intermediate layer, and an outer or third layer formed from a material comprising a non-phthalate plasticizer, such as TOTM, DOA, DOTP, or combinations thereof. The multilayer tubing may be suitable for carrying a fuel, or other flammable substances therethrough, and resists delamination between layers when exposed to high humidity climates.

Abstract: A tubular including a plurality of first-type layers; and a plurality of second-type layers each disposed between a pair of adjacent first-type layers, wherein the plurality of first-type layers includes at least two first-type layers, wherein the plurality of second-type layers includes at least two second-type layers, and wherein a Melt Flow Index, MFI1, of each of the plurality of first-type layers is different than a Melt Flow Index, MFI2, of each of the plurality of second-type layers, as measured at a same temperature. In an embodiment, at least one of the first-type layers and the second-type layers is adapted to provide a barrier against escape of gases, liquids, or a combination thereof from the tubular.
