Abstract: A method of manufacturing a polyolefin foam sheet composition includes extruding a polyolefin sheet, irradiating the extruded sheet to obtain a physically crosslinked sheet, foaming the physically crosslinked sheet with heat to obtain a foamed layer, and skiving the foamed layer to obtain a foam sheet with at least one skived surface. The surface roughness of the skived surface of the foam sheet is different from the surface roughness of an unskived surface.

Abstract: PLA polymers that can be expanded into microporous articles having a node and fibril microstructure are provided. The fibrils contain PLA polymer chains oriented with the fibril axis. Additionally, the PLA polymers have an inherent viscosity greater than about 3.8 dL/g and a calculated molecular weight greater than about 150,000 g/mol. The PLA polymer article may be formed by bulk polymerization where the PLA bulk polymer is made into a preform that is subsequently expanded at temperatures above the glass transition temperature and below the melting point of the PLA polymer. In an alternate embodiment, a PLA polymer powder is lubricated, the lubricated polymer is subjected to pressure and compression to form a preform, and the preform is expanded to form a microporous article. Both the preform and the microporous article are formed at temperatures above the glass transition temperature and below the melting point of the PLA polymer.
