Abstract:
1. Molded articles selected from express couplings which connect hose or pipeline, connectors for fuel lines, fuel filter housings, tank filling connections, vent lines or laminated materials for fuel lines, produced from a polymer mixture comprising: a) more than 50% by weight of partially crystalline aliphatic polyamides, wherein the quantitative ratio of the aliphatic carbon atoms to amide bonds in the aliphatic polyamides being in the range of 8:1 to 12:1; b) less than 50% by weight of a predominantly partially crystalline mixture of partially aromatic polyamides, having, in addition to hexamethyleneterephthalamide (6T) units, further partially aromatic and/or aliphatic amide units comprising wherein the polymer mixture has a reduced fuel permeability in comparison with polyamide 11 or polyamide 12.
