Abstract
Microtextured elastomeric materials having at least one elastomeric core layer or region and at least one skin layer wherein the skin layer has a semi-crystalline or amorphous polymer and an elastomeric block copolymer or pressure sensitive adhesive, the combination of which is less elastic than the core layer and will undergo permanent deformation at the stretch percentage that the elastomeric laminate will undergo. The materials are suited for use in applications such as respirators.
