Abstract:
The invention relates to a hose having at least one barrier layer inner layer and an outer layer, wherein the barrier layer is obtainable by extrusion of a mixture comprising a) at least one thermoplastic fluoropolymer, b) at least one fluororubber and a crosslinking agent and/or at least one fluororubber elastomer and c) at least one carbon filler selected from carbon black, in particular conductivity carbon black, graphene, carbon nanofillers, in particular carbon nanotubes, carbon nanohorns, or a combination thereof in an amount of 0.05% by weight to 20% by weight of the carbon filler(s), or irradiated PTFE, and vulcanization. The hose exhibits a high fuel, diesel and oil stability and dynamic capability.
