From the results according to Table 1 shows that the hose according to the invention has a higher flexibility and concomitantly a significantly improved kink resistance, as the hose of the prior art, especially against the background that in the hose of the prior art a slightly larger wall thickness is present.

Despite the higher flexibility and the improved durability of the hose according to the invention, this has a high pressure resistance compared to the hose of the prior art.

The hose according to the invention has a pressure resistance of approximately 15 bar at 23 ° C., while the hose of the prior art shows a pressure resistance of approximately 24 bar at 23 ° C.

Due to the special selection of the polymer materials for the layer or layers of the tube according to the present invention, this also has a high temperature resistance, which is up to 80 ° C as a continuous use temperature and briefly up to 95 ° C, which further extends the possibilities of its use ,

The hose is widely used for receiving, storing and directing fluids in means of transport, buildings, apparatus and machinery.

Thus, it is thus possible, for example, a fluid supply and in particular a drinking water supply in a building, in a living or working container, but also in a means of transport, such as in a caravan, in a motorhome, in a train carriage, in an airplane, on a Build a ship and the like.

Furthermore, the hose can be used very advantageously in machinery and apparatus to be laid there in tight spaces under narrow radii, as is the case, for example, in devices of domestic appliance technology, such as. a. in dishwashers, washing machines, irons, coffee machines, beverage dispensers and the like is necessary.
