The elastomer laminate (1) comprises an elastomer cover layer (3) composed of a thermoplastic elastomer, and a cover layer that has a microtexture and a foam structure with pores (4) and is composed of a polymer having a lower elasticity than a material of a carrier layer (2). The microtexture is produced by stretching the laminate beyond an elasticity limit of the cover layer and elastic recovery of the stretched laminate, by uniaxial stretching of the laminate in an extrusion direction and by biaxial stretching of the laminate. The elastomer laminate (1) comprises an elastomer cover layer (3) composed of a thermoplastic elastomer, and a cover layer that has a microtexture and a foam structure with pores (4) and is composed of a polymer having a lower elasticity than a material of a carrier layer (2). The microtexture is produced by stretching the laminate beyond an elasticity limit of the cover layer and elastic recovery of the stretched laminate, by uniaxial stretching of the laminate in an extrusion direction and by biaxial stretching of the laminate. The pores are uniformly distributed in the cover layer, and are smaller than a thickness of the cover layer before stretching of the laminate. The cover layer further has a cell structure having a polymer matrix and pores that extend in part over an entire thickness of the cover layer. The cover layer has a thickness, measured before stretching of the laminate, of 1-20 mu m, and the carrier layer has a thickness, measured before stretching of the laminate, of 15-150 mu m. An independent claim is included for a method for producing an elastomer laminate. |
