Document Type and Number:
Japanese Patent JP4055344
Kind Code:
B2
Abstract:
In a fuel hose composed of an inner single layer or multilayer of a fluororesin and an outer single layer or multilayer of a thermoplastic resin, any two materials for the layers have a ratio 1 : 40 or below in melt viscosity as expressed in Pa.s. The wall formed by having its inner and outer layers co-extruded is free from any unevenness in thickness that would occur if their materials had a larger ratio in melt viscosity. Thus, it is impermeable to fuel, and has an improved adhesion between its inner and outer layers.
