Abstract: A temperature resistant, structural polymer nanocomposite foam may be formed from an amorphous or semi-crystalline, thermoplastic polymer matrix and a nano smectite clay intercalated and/or exfoliated in the polymer. The nano smectite clay may be coated with an organophilic surfactant. A polymer foam may be formed by forming a precursor material from an amorphous or semi-crystalline, thermoplastic polymer. The precursor material may be infused with a supercritical fluid at a process temperature of less than approximately 340° C. and a process pressure of at least 10 MPa. The precursor material may be foamed using the supercritical fluid by suddenly decreasing the pressure on the precursor material. The precursor material may also contain a nano smectite clay. It may be formed into a molded preform. The polymer foam formation process may include net-molding.

Abstract: A solid state foaming process permits the use of up to 100% recycled pre- and post-consumer polymer for the manufacture of foamed polymer material and thermoformed foamed polymer articles. The process enables the optional formation of integral unfoamed skins of controllable depth and crystallinity on foamed polymeric materails suitable for a wide variety of applications. Because this process does not alter the underlying chemistry of the material all scrap from the manufacturing process may be reused without additive to form new foamed polymeric materials and articles.

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.

Abstract: A resin composition containing thermoplastic resin and a flame retardant is sufficiently kneaded and molded and carbon dioxide in a supercritical state is caused to permeate into it. Subsequently, the resin composition is degassed by cooling and/or pressure reduction. As a result of degassing, a resin foam body 1 having a fine and uniform micro-cellular foam structure is obtained. The resin foam body 1 has a cyclic structure in which a resin phase 2 and a pore phase 3 are continuous and intertwined. The obtained resin foam body 1 can suitably find applications such as home OA parts, electric and electronic parts and automobile parts that are required to be highly strong, lightweight and nonflammable.
