Abstract:
The present disclosure relates to polishing pads which include a polishing layer, a porous substrate and an interfacial region. The present disclosure relates to a method of making the polishing pads. The present disclosure relates to a method of polishing a substrate, the method of polishing including: providing a polishing pad according to any one of the previous polishing pads; providing a substrate, contacting the working surface of the polishing pad with the substrate surface, moving the polishing pad and the substrate relative to one another while maintaining contact between the working surface of the polishing pad and the substrate surface, wherein polishing is conducted in the presence of a polishing solution.
Abstract:
A wire management article includes a base sheet and a plurality of wire management elements. The base sheet has a major surface from which the wire management elements project. The wire management elements define a plurality of channels. Each channel is configured to retain at least one wire. The wire management article may include a cover sheet releasably attached to the base sheet. The wire management article may be part of a wire management system.
Abstract:
An article includes a polishing layer that includes a plurality of raised cells separated by a plurality of channels. Each of the plurality of raised cells includes a microstructured working surface, a substantially vertical channel surface, and an offset surface between an edge of the working surface and an upper edge of the channel surface. The microstructured working surface includes a plurality of microstructures. Tops of the plurality of microstructures define a top plane and bases of the plurality of microstructures define a base plane. The substantially vertical channel surface defines a wall of a channel of the plurality of channels and the channel surface defines a channel plane. The offset surface includes a nonplanar portion of displaced material. The displaced material defines a displacement plane that is below the base plane or within a tolerance of the top plane.

Abstract:
Polymeric multilayer film having first and second generally opposed major surfaces, and comprising first, second, and third layers, an array of blind openings between the first and second major surfaces, and an average thickness, wherein the first, second, and third layers each have a first average thickness excluding any thickness said first, second, and third layers having in any of the blind openings, wherein the first and second layers extend into the first average thickness of the third layer, wherein each of the first, second, and third layers each have a second average thickness (including a thickness of zero) in the blind holes, wherein the second average thickness of the first and third layers are each greater than zero, and wherein the ratio of the first average thickness of the second layer to the second average thickness of the second layer is at least 2.1; and method of making the same. Embodiments of polymeric multilayer film described herein are useful, for example, for acoustic absorption.
Abstract:
Polymeric foam layer having a thickness up to 25,700 micrometers, having first and second opposed major surfaces, and comprising foam features extending from or into the first major surface by at least 100 micrometers, and having a Tg in a range from −125° C. to 150° C., wherein the first and second opposed major surfaces are free of exposed internal porous cells (i.e., less than 10 percent of the surface area of each of the first and second major surface has any exposed porous cells) and wherein at least 40 percent by area of each major surface has an as-cured surface; and methods of making the same. Exemplary uses of polymeric foam layers described herein including a finishing pad for silicon wafers and vibration damping.
