EXPANDABLE BAFFLE/SEAL WITH PATTERN OF PROJECTIONS AND VOIDS

摘要

A generally planar baffle is disclosed. The baffle has an expandable layer coupled to an adhesive layer. The expandable layer has on its external surface a pattern of projections and a pattern of voids relative to the projections, such that the projections define a first thickness of the expandable layer and the voids define a second thickness of the expandable layer, wherein the first thickness is greater than the second thickness.
