    Abstract: A variety of foams and foam components are provided, including foam components for articles of footwear and athletic equipment. The articles include a composition having a foam structure, wherein the composition includes a thermoplastic copolyester elastomer comprising: (a) a plurality of first segments, each first segment derived from a dihydroxy-terminated polydiol; (b) a plurality of second segments, each second segment derived from a diol; and (c) a plurality of third segments, each third segment derived from an aromatic dicarboxylic acid. Methods of making the compositions and foams are provided, as well as methods of making an article of footwear including at least one of the foam components. In some aspects, the foams and foam components can be made by extrusion or injection molding to foam the polymeric composition, or extrusion or injection molding to foam the polymeric composition followed by compression molding of the foam.

    Abstract: Components for articles of footwear and athletic equipment including a foam are provided. The foam portion of the components and articles include a composition which includes a thermoplastic copolyester, the composition having a foam structure. A polymer layer is provided on at least on surface of the foam portion. The polymer layer can control or reduce the water uptake of the foam portion. Methods of making the compositions, foams, and components are provided, as well as methods of making an article of footwear including one of the foam components. In some aspects, the foams and foam components can be made by injection molding, or injection molding followed by compression molding.

    Abstract: A method for making a low density foamed article includes placing a desired amount of thermoplastic polyurethane foam beads in a cavity of an injection mold and closing the mold; combining in an extruder connected to the mold a molten polymer selected from the group consisting of thermoplastic polyurethane elastomers and thermoplastic ethylene-vinyl acetate copolymers with both a physical or chemical blowing agent other than a supercritical fluid present in an amount up to about 15 wt % based on molten polymer weight and a supercritical fluid that is at least one of about 0.1 to about 5 weight percent of supercritical CO2 based on molten polymer weight or about 0.1 to about 4 weight percent of supercritical N2 based on molten polymer weight, to form a mixture and injecting the mixture into the mold and foaming the mixture to form the low density foamed article.
