Automotive fuel hose

摘要

An automotive fuel hose of low fuel permeability, and excellent in impact resistance, hydrolysis resistance, and inter-layer adhesion. The automotive fuel hose comprises: a tubular inner layer (1) comprising a fluororesin having a functional group; and a low fuel permeability layer (2) comprising a polyester resin having a naphthalene ring; the inner layer in which fuel is adapted to flow; the low fuel permeability layer being laminated onto the inner layer such that respective mating interfaces contact each other.
