The present disclosure relates to multi-layer pipes that are fuel resistant and resistant to delamination. In one aspect, the present disclosure is a cyclic fluoropolymer layer formed from at least 75 wt% fluoropolymer (eg, at least 75 wt% PVDF polymer), said fluoropolymer layer having outer and inner surfaces; and said fluoro. A cyclic thermoplastic layer arranged around a polymer layer and formed from at least 75% by weight of a thermoplastic (eg, thermoplastic polyurethane, thermoplastic polyamide and / or thermoplastic polyester) of the fluoropolymer layer. Provided is said tube, which comprises the thermoplastic layer having an inner surface and an outer surface in contact with the outer surface, wherein the fluoropolymer layer is covalently bonded to the thermoplastic layer. |
