Self-supporting waterproof and at the same time breathable film, which also shows an antistatic behavior, the film has a DIN coefficient of friction less than 0.8 and the film consists of thermoplastic polyurethane elastomer resins, whose melt index at 190 ° C and a test load of 10 kg is at most 70, the soft segment of these elastomer resins consisting of polyethylene oxide and / or containing ethylene oxide reaction products and the relative mass fraction of the soft segment in the polyurethane resin being between 35 mass% and 60 mass%, in each case based on the total mass of the used Polyurethane. |
