Abstract
An absorbent article may have at least one stretch zone comprising a slow recovery elastomer wherein the slow recovery elastomer exhibits a normalized unload force of greater than about 0.04 N/mm2 at 37° C.; and the slow recovery elastomer exhibits at least about 20% post elongation strain at 22° C. after 15 seconds of recovery from a 400% strain. The absorbent article may additionally comprises one or more of a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core, an ear, a side panel, a waist feature, a fastener component, a leg cuff, a gasketing cuff, and a barrier cuff, wherein the feature comprises at least a part of the stretch zone.
