The invention relates to an elastic membrane comprising an elastomer having an elongation at tear of greater than 150%, measured in accordance with DIN 53504, wherein the thermoplastic elastomer (P1) comprises a polyurethane elastomer based on the following components: 11 to 79 wt% of a mixture of at least one diol (D1) and at least one isocyanate (I1), 21 to 89 wt% of at least one compound (C1) having at least two groups reactive with respect to isocyanate. The invention further relates to a method for producing such an elastic membrane comprising an elastomer having an elongation at tear of greater than 150%, measured in accordance with DIN 53504. The invention further relates to an elastic membrane comprising an elastomer having an elongation at tear of greater than 150%, measured in accordance with DIN 53504, obtained or obtainable by the method, to an elastic fabric comprising a fabric and at least one elastic membrane laminated on, having an overall elongation at tear of greater than 150%, measured in accordance with DIN 53504, and to the use of the elastic membrane or an elastic membrane obtained or obtainable by the method for coating fabrics.
