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