摘要：
A flexible hose or a tubing having a barrier layer of polyamide 6 having an impact modifier, and/or branched molecular structure, a flexural modulus of 1 to 2 GPa and/or a tensile elongation of 100% or more. The hose may have additional layers such as an HNBR rubber inner tube, an EVM/CPE rubber blend outer cover, a textile or wire reinforcement, or the like. Permeability to ethanol- and methanol-containing fuels is very low. Permeability to B20 biofuels is very low.
