Abstract: Coextruded polymeric layer having first and second opposed major surfaces, the coextruded polymeric layer comprising foam and the coextruded polymeric layer comprising features extending from or into the first major surface by at least 100 micrometers, the first major surface comprising a first material having a first percent elongation at break, the second major surface comprising a second material having a second percent elongation at break, wherein the first percent elongation at break is greater than 100 percent of the second percent elongation at break. Coextended polymeric layers described herein are useful, for example, in vibration damping applications (e.g., a vibration damping laminate comprising a kinetic spacer comprising the coextruded polymeric layers).

Abstract: A condensation management apparatus comprises a first microstructured film arranged to condense water vapor on a substantially vertical surface of a component. The first film comprises channels disposed on first and second major surfaces of the first film and dimensioned to support capillary movement of condensate. The channels have a channel axis substantially parallel with a longitudinal axis of the first film. The longitudinal axis of the first film is tilted at a tilt angle of at least 4 degrees with respect to an axis normal to a direction of gravity. Openings in the channels are disposed at one or both end edges of the first film. The openings provide condensate release locations of the first film. A second film is disposed over a portion of the first film. The second film attaches the first film to the substantially vertical surface of the component.

Abstract: Polymeric multilayer film having first and second generally opposed major surfaces, an array of openings extending between the first and second major surfaces, and a thickness greater than 125 micrometers, wherein there are at least 30 openings/mm2, and wherein the openings each have a series of areas through the openings from the first and second major surfaces ranging from minimum to maximum areas, and wherein the minimum area is not at at least one of the major surfaces. Embodiments of polymeric multilayer film described herein are useful, for example, for filtration and acoustic absorption.
