Abstract: A thermoplastic material having a thickness includes a polymer having a microstructure that includes a plurality of closed cells disposed in an inner region of the material's thickness. Each of the plurality of closed cells contains a void and each of the cells has a maximum dimension extending across the void within the cell that ranges between 1 micrometer and 500 micrometers long. The thermoplastic material also includes a substantially solid skin disposed in an outer region of the material's thickness. The skin includes a surface having a surface energy and a texture that increases the surface energy to more than 38 dynes per square centimeter.
