Abstract: Biomaterial-based elastomeric materials are disclosed, as are methods for making and using such fibrous materials. In some embodiments, a biomaterial textile composition includes a mixture of a thermoplastic elastomer and a second polymer. The biomaterial textile compositions of the disclosure are characterized by desirable combinations of material properties, e.g., elastic modulus and hardness, that make the materials especially suitable for various applications, particularly as leather analogs and similar textiles.

Abstract: Molded polymer foam articles are described as having a novel foam structure. The polymer foam articles include a continuous polymer matrix defining a plurality of pneumatoceles therein which is present throughout the entirety of the article. The surface region is further characterized as having compressed pneumatoceles. The novel foam structure is achieved even when molding polymer foam articles comprising a shape and volume wherein a sphere having a diameter between 2 cm and 1000 cm would fit within the article in at least one location without protruding from a surface of the article, and the article further has a total volume of more than 1000 cm3. Methods of making a stabilized molten polymer foam, and of making a molded polymer foam article using the stabilized molten polymer foam are also described.
