The adhesive tape comprises a backing layer (hard phase) and a soft phase that are arranged in sequence and directed towards a substrate to be covered, where the hard phase and the soft phase comprise a polymer foam, a viscoelastic composition and/or an elastomeric composition. A thickness of the hard phase is = 150 mu m. A thickness of the soft phase is 200-1800 mu m. A ratio of the thickness of the soft phase to the thickness of the hard phase is >= 4. The flexural stiffness of the hard phase is 10 mN/mm. |
