More Information
Summary:The invention relates to a high-pressure hose with a pressure classification of H70 according to DIN ISO 19880-5 and/or a burst pressure of at least 3500 bar, wherein the hose has a layer construction comprising an inner barrier layer made of aliphatic polyketone, at least one reinforcement layer, and an outer layer made of a polymer material. Such high-pressure hoses are characterized by a property profile which is very advantageous for an application using hydrogen at high pressures. The invention also relates to methods for producing such hoses, to tank filling devices equipped with such hoses, and to uses of corresponding high-pressure hoses for transferring hydrogen from a storage container into a tank.
