    摘要: A heated roll suitable for use as a fuser roll in a xerographic processes is formed from a sheet of flexible, resilient, polyimide foam. An electrical heating circuit is adhesively secured thereto. The circuit is preferably disposed between a pair of polyimide film sheets which, in turn, are secured to the foam.

    摘要: A laminate and a method for its preparation comprising a polyimide foam, a fire-resistant, heat-activated adhesive overlaying a skin on the foam and a polyimide film adhered to the skin, with the laminate being prepared by contacting a foam in contact with the adhesive and film under heat and pressure to simultaneously form a skin on one surface of the foam and bond the polyimide film through the adhesive to the skin.

    摘要: A body of cured polyimide foam is treated with steam to produce a non-flexible, non-resilient cellular structure. A molding member is impressed into this structure to a depth less than the full thickness of the structure. The structure is then cured to polyimide foam with the molding member removed therefrom either before, during or after the curing has been completed. The resultant articles, which may be laminated, are useful as panels to dampen vibration and sound, and to provide thermal insulation. In addition the articles are flame resistant and flexible.

    摘要: Cured polyimide foam is exposed to an atmosphere of steam at elevated temperature and pressure for a period of time sufficient to convert the foam into a non-flexible, non-resilient recurable cellular material. Preferably the process is conducted such that the cellular material is recurable to a flexible resilient foam having tensile strength properties similar to the tensile strength properties of the original cured polyimide foam subjected to the process. Before recuring, the non-flexible, non-resilient recurable cellular material may be shaped or contoured, and then recured. For example, by impressing shaped articles into the recurable material followed by recuring, shipping/storage containers for the articles are readily produced.
