Abstract: Disclosed herein are methods for making expanded foamed polymeric panels from solid monolithic semi-crystalline thermoplastic material sheets having a first thickness, density, and volume. In one embodiment, the method comprises: absorbing an effective amount of a plasticizing gas into the semi-crystalline thermoplastic material sheet to yield a reversibly plasticized semi-crystalline thermoplastic material sheet that is differentially impregnated with the plasticizing gas to define a non-uniform gas concentration gradient across the initial first thickness; and heating the plasticized semi-crystalline thermoplastic sheet to yield the foamed polymeric panel, wherein the foamed polymeric panel comprises (1) a second thickness that is at least about three and half times greater than the first initial thickness, and (2) a non-uniform second density level that is less than the first density level. In another embodiment, the foamed polymeric panel also comprises (3) a second volume that is at least 5 times greater than the first volume.

Abstract: This invention provides packages and containers produced by a solid state method for the manufacture of foamed polymeric material. The packages are suitable for pre-cooking or sterilization, insulated transport, cooking vessel, reheating, and storage of food. The gas impregnated thermoforming (GIT) process includes interleaving an article of raw polymeric material with a gas channeling means; exposing the article to a non-reacting gas at elevated pressure to achieve a desired concentration of gas within the polymer, thereby forming a partially gas-saturated article, separating it from the gas channeling means, then decompressing, foaming and forming it at a temperature below the material's melt temperature; and finally trimming it to produce a finished foamed polymeric material and recyclable scrap solid state process foamed polymer.

Abstract: A first polymer (preferably in granular form) is exposed to a gas at a pressure higher than atmospheric pressure to introduce the gas into the polymer. This occurs at a temperature from the glass transition temperature to the melting temperature when the first polymer is crystalline or semi-crystalline in nature, or at a temperature below the glass transition temperature when the first polymer is amorphous in nature. Optionally, the gas-laden polymer may then be mixed with a second polymer. The polymer is then melted to produce a foamed article.

Abstract: A porous, starch-based pigment and filler product, which comprises a foam, which contains foam bubbles, the average size of which is less than approximately 10 micrometres, and a method of manufacturing it. From the starch, microporous foam can be prepared, which can be stabilized to microcapsules. By means of a suitable choice of the inner diameter and the wall thickness of these capsules the light scattering ability of the material is maximized, which means that the structure has good opacity properties. Good strength properties in relation to the capsule mass is also characteristic of the micro capsule structure.

Abstract: Fluoropolymer materials containing tetrafluoroethylene monomers, such as PTFE, are significantly swollen by supercritical carbon dioxide at high temperatures and pressures. The swollen fluoropolymer is processable by molding, extrusion, and other techniques. In addition, the fluoropolymer may be sintered at significantly lower temperatures compared to a nonswollen fluoropolymer material. The melting temperature of fluorinated polymers containing tetrafluoroethylene and triflouroethylene monomers which are swollen with supercritical carbon dioxide is significantly reduced, thereby permitting manufacturing operations such as extruding and molding to be performed at lower temperatures and with reduced risk of decomposition.
