Abstract

The invention in relates in particular to a rubber composition able to be extruded to form an inner layer of a fuel hose for a motor vehicle, a method for preparing this composition, this hose and a fuel feed circuit of a motor vehicle incorporating it. This composition is based on at least one fluoroelastomer (FKM) and includes a filler and a micronised powder of at least one fluorinated thermoplastic polymer which are dispersed in said at least one fluoroelastomer. According to the invention, the composition includes said micronised powder according to a quantity greater than 20 phr (phr: parts by weight per 100 parts of elastomer(s)), and the filler includes at least one inorganic filler having lamellas which has an aspect ratio greater than 30 and which is based on a phyllosilicate chosen from kaolinite and micas, or is based on a talc.
