Low-permeation flexible fuel hose

A flexible hose or a tubing having a barrier layer of polyamide 6 having branched molecular structure and an impact modifier, and/or a flexural modulus of 1 to 2 GPa and a tensile elongation of 100% or more. The hose may have additional layers such as an inner tube, an outer cover, a textile or wire...

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