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.

Abstract: Polymeric layers (50) comprising an array of blind openings (56) extending into the first major surface (52, 10111, 11211), but not through the second major surfaces (54, 10112, 11212). The blind openings each have a series of areas through the openings from the first major surface towards the second major surfaces ranging from minimum to maximum areas, where for at least a majority of the blind openings the minimum area is not at the first major surface. At least a portion of the first major surface comprises a first material and extends up to, but not into the second major surface. At least a portion of the second major surface comprises a second, different material. Methods for making the polymeric layers are also disclosed. Polymeric layers are useful, for example, as components in personal care garments such as diapers and feminine hygiene products. They can also be useful for filtering (including liquid filtering) and acoustic applications.

Abstract: Polymeric layers (50) comprising an array of openings (56) extending between the first and second major surfaces (52, 54), wherein the openings (60) each have a series of areas through the openings from the first and second major surfaces ranging from minimum to maximum areas. There is a total area and a total open area for each of the first and second major surfaces, wherein the total open area for each of the first and second major surfaces is not greater than 50 percent of the total area of the respective major surface. For at least a majority of the openings (56), the minimum area is not at either major surface. Methods for making the polymeric layers are also disclosed. Polymeric layers are useful, for example, as components in personal care garments such as diapers and feminine hygiene products and medical skin applications where breathability is desired. They can also be useful for filtering (including liquid filtering) and acoustic applications.
Abstract translation: 聚合物层（50）包括在第一和第二主表面（52,54）之间延伸的开口阵列（56），其中开口（60）各自具有穿过来自第一和第二主表面的开口的一系列区域 从最小到最大。 第一和第二主表面的总面积和总开口面积，其中第一和第二主表面中的每一个的总开口面积不大于相应主表面总面积的50％。 对于至少大部分开口（56），最小面积不在任何主表面。 还公开了制备聚合物层的方法。 聚合层例如可用作个人护理服装中的组分，例如尿布和女性卫生用品以及需要透气性的医用皮肤应用。 它们也可用于过滤（包括液体过滤）和声学应用。

Abstract: Provided are conduits for air flow that are capable of reducing noise and related methods. The provided conduits include a first section that is tubular and substantially non-perforated and a second section with at least a portion having a multiplicity of microperforations that provide an average flow resistance of from 50 MKS Rayls to 8000 MKS Rayls therethrough. The second section is either (a) tubular and connected in series with the first section, with an outer surface of the second section being in fluid communication with an outer surface of the conduit, or (b) disposed within the first section.
