    Abstract: There is provided a resin foam excellent in deformation recovery performance after compressive deformation. The resin foam of the present invention has a stress retention to be defined below of not less than 70%: stress retention (%)=(compressive stress after 60 seconds)/(compressive stress after 0 seconds)×100 wherein a resin foam in a sheet form having a thickness of 1.0 mm is compressed in the thickness direction so that the resin foam has a thickness of 20% of the initial thickness, and the compression state is held; and the compressive stress immediately after compression is defined as “compressive stress after 0 seconds,” and the compressive stress 60 seconds after holding the compression state is defined as “compressive stress after 60 seconds.”

    Abstract: A method for making a shapeable article from poly(lactic acid) includes treating solid poly(lactic acid) that results in the solid poly(lactic acid) having a crystallinity of at least 20% by weight based on the weight of the solid poly(lactic acid) and a gas concentration of 6% to 16% by weight based on the weight of the solid poly(lactic acid); and heating the solid poly(lactic acid) having said minimum crystallinity and gas concentration to produce a cellular poly(lactic acid) article that is shapeable. The shapeable cellular poly(lactic acid) article is advantageous in that the article can be further shaped by heat and/or pressure (or vacuum), such as via thermoforming, into a variety of useful products.

    Abstract: Disclosed herein are methods and pressure vessels for solid-state microcellular processing of thermoplastic rolls and sheets. In one embodiment, the present invention is directed to a method for making a gas impregnated interleaved roll, which method comprises: providing a pressure vessel having an internal pressure chamber and a rotatable shaft horizontally positioned within the pressure chamber; placing an interleaved roll about the rotatable shaft and within the pressure chamber, wherein the interleaved roll is made from a thermoplastic material sheet interleaved together with a gas-channeling material sheet; pressurizing the pressure chamber to a selected pressure; rotating the rotatable shaft having the interleaved roll thereabouts (thereby rotating the interleaved roll) while under pressure for a selected period of time; and depressurizing the internal chamber to yield the gas impregnated interleaved roll. In other embodiments, the invention is directed to multi-chambered pressure vessels for gas impregnation of thermoplastic rolls, sheets, and films.
