Abstract (en)

[origin: EP2050865A1] The cover has a layer (1) partially connected with a textile surface unit (2) in a planar manner by an elastomer adhesive, where the layer contains viscoelastic polymer foam. The textile surface unit exhibits an elastic modulus in a specific range. The polymer foam exhibits compression hardness in a specific range during 40 percentage of compression. The polymer foam exhibits a hysteresis between 20 and 70 percentage during the provision of the compression hardness. The polymer foam is selected from a group of polyurethane foam or a cross-linked impact foam of synthetic or natural latex. An independent claim is also included for a method for producing a ground cover.
