Abstract
An elastomer laminate has an elastomer carrier layer composed of a thermoplastic elastomer, and at least one microtextured cover layer composed of a polymer that has a lower elasticity than the material of the carrier layer. The microtexture is produced by stretching the laminate beyond the elasticity limit of the cover layer and elastic recovery of the stretched laminate. The microtextured cover layer contains a plurality of pores.
Claims8
An elastomer laminate comprising:
- a single elastomer carrier layer composed of a thermoplastic elastomer, and
- a single layer or at most two layers having a microtexture and being composed of a polymer that has a lower elasticity than a material of the single carrier layer, said single layer or at most two layers containing a plurality of pores, forming a cover layer or cover layers of the elastomer laminate such that the single layer or at most two layers form at least one exterior surface of the elastomer laminate, and said single layer or at most two layers consisting of a foam structure with ruptured pores,
- wherein the microtexture consists of wrinkles and pores that are open toward the exterior surface and is produced by stretching the laminate beyond an elasticity limit of the cover layer or cover layers and elastic recovery of the stretched laminate.
