摘要： The invention is directed in part to an article that includes a polymer foam having a surface with surface microstructures, the surface microstructures have at least one extent or dimension of about 10 microns or more, preferably 50 microns or more. A maximum extent (unless it is a continuous rib-like structure) the microstructure is about 300 microns or less, preferably 200 microns or less, and generally a maximum height of 1000 microns or less, preferably 750 microns or less and a minimum height of 200 microns or more, preferably 300 microns or more. The foamed article may be provided in a variety of shapes, including a rod, a cylinder, a sheet, etc. In a preferred embodiment where the foam is provided in the form of a sheet, the foam has a pair of major surfaces, one or both of which can be provided with surface microstructures. The foam backing and microstructures include a plurality of voids, which voids are preferably of a mean size substantially less than the smallest cross-sectional dimension or extent of the microstructures.

摘要： A toner supply roll including a cylindrical soft polyurethane sponge structure formed on an outer circumferential surface of a metal shaft by foam molding of a polyurethane material in a mold cavity of a mold. The sponge structure having hardness of 350 g or lower includes a skin layer having a network of cells and openings open in its outer circumferential surface and communicating with respective ones of the cells located adjacent to the skin layer, such that the openings are substantially aligned with central portions of the respective ones of the cells in axial and circumferential directions of the sponge structure. Each opening has a size of 100-800 .mu.m, and a total area of the openings is at least 20% of the total surface area of the skin layer. The sponge structure has a plurality of protrusions formed on the outer circumferential surface of the skin layer so as to extend linearly or helically in the axial direction of the sponge structure. The protrusions have a height of 20-3000 .mu.m and are arranged in a circumferential direction of the sponge structure with a pitch of 300-3000 .mu.m, so that the skin layer is provided with recesses each interposed between the adjacent protrusions. Methods of producing the roll are also disclosed.

摘要： A trim article includes an outer casing having an inner surface defining an interior portion of the outer casing. The outer casing includes a front surface having a plurality of through apertures disposed thereon. A core portion is disposed within the interior portion of the outer casing and includes first and second portions having variated densities relative to one another. The first and second portions include lattice matrices having variated patterns of interconnected links and associated cells that provide variated force deflection parameters between the first and second portions of the core portion. The outer casing and the core portion are integrated to define a monolithic structure comprised of a common material.
