Abstract: The present invention relates to thermoplastic hollow vessels, tanks, drums and other industrially applicable housings. The invention is adaptable as plastic fuel tanks with low fuel permeability, e.g., less than 5 g.·mm/m2 day as a mono-layer structure. These vessels exhibit good sub 0 0C impact properties and are formed by relatively inexpensive blow molding or rotomolding processes. Disclosed are mono-layered hollow vessels comprising an uncompatibilized, fused blend composition of polyoxymethylene, thermoplastic polyurethane and a copolyester. In one embodiment mono-layered hollow vessels comprise uncompatibilized, fused polyoxymethylene, thermoplastic polyurethane and copolyester in the respective wt. amounts of 100, 5-15 and 5-15. According to a more preferred aspect the wt. ratio of thermoplastic polyurethane to copolyester is from 1:3 to 3:1.

Abstract: Composites are prepared from resin-impregnated flexible graphite materials. Impregnated materials are compressed and cured at elevated temperature and pressure to form structures suitable for uses such as electronic thermal management (ETM) devices, supercapacitors and secondary batteries.

Abstract: A material useful in a process for embossing a flexible graphite sheet is presented. The inventive material is a flexible graphite sheet which has a preselected void condition which provides the capability of controlling the morphology, and thus the functional characteristics, of the resulting embossed sheet.

Abstract: An improved method enables preparation of articles for a variety of applications, including embossing or otherwise shaping to form a variety of articles. A plurality of thin, preferably resin-impregnated, flexible graphite sheets are arranged to form zones in a composite material having a graded density or other characteristic. Variation of properties between zones in the stock material formed is useful for achieving a desired set of properties in the formation of articles such as those useful in electrochemical fuel cells and double-layer capacitors.

Abstract: A flexible graphite sheet material having improved molding characteristics is provided by effecting resin impregnation such that the resin profile across one of the dimensions of the sheet is non-uniform.

Abstract: A process for preparing a gas permeable flexible graphite sheet is presented. The process includes providing graphite flakes; admixing the graphite flakes with a sacrificial additive to form a graphite mixture; compressing the graphite mixture into a sheet having sacrificial additive dispersed therethrough; and treating the sheet to at least partially remove the sacrificial additive to form a permeable flexible graphite sheet.

Abstract: Laminates are prepared from resin-impregnated flexible graphite sheets. Impregnated sheets are calendered and layers of the calendered sheets, which may also be coated with a resin adhesive, are stacked into structures which optionally contains layers of metals or plastics. After curing at elevated temperature and pressure, 2500 psi and 150° C., the laminates form dense machinable structures suitable for uses such as electronic thermal management (ETM) devices.
