In one embodiment, the invention is directed to a multi-layer foamed polymeric article of manufacture, comprising: a non-laminated multi-layer thermoplastic material sheet, wherein the multi-layer thermoplastic material sheet has first and second discrete outer layers sandwiching a plurality of discrete inner foamed layers, and wherein the two outer layers and plurality discrete inner foamed layers are integral with one another. The thermoplastic material may be a semi-crystalline polymer such as, for example, PET (polyethylene terephthalate), PEEK (polyetheretherketone), PEN (polyethylene naphthalate), PBT (polybutylene terephthalate), PMMA (polymethyl methacrylate), PLA (polylactide), polyhydroxy acid (PHA), thermoplastic urethane (TPU), or blends thereof. The two outer layers may be unfoamed skin layers having smooth outer surfaces, and the discrete inner foamed layers may be microcellular.

A heat-insulating housing (21) includes: a wall body; and an open-cell resin body (4) of thermosetting resin with which a heat-insulating space formed by the wall body is filled by integral foaming, the open-cell resin body including: a plurality of cells (47); a cell film portion (42); a cell skeleton portion (43); a first through-hole (44) formed so as to extend through the cell film portion; and a second through-hole (45) formed so as to extend through the cell skeleton portion, wherein the plurality of cells communicate with one another through the first through-hole and the second through-hole.

A multilayer polymer film for multipacks is provided that includes at least two layers formed from polyester and additives, in which a first layer is porous and a second layer contains an inorganic filler. Multipacks thermoformed from the multilayer polymer film are equipped with snap incisions.

Systems and methods are disclosed herein for a pressure tolerant energy system. The pressure tolerant energy system may comprise a pressure tolerant cavity and an energy system enclosed in the pressure tolerant cavity configured to provide electrical power to the vehicle. The energy system may include one or more battery cells and a pressure tolerant, programmable management circuit. The pressure tolerant cavity may be filled with an electrically-inert liquid, such as mineral oil. In some embodiments, the electrically-inert liquid may be kept at a positive pressure relative to a pressure external to the pressure tolerant cavity. The energy system may further comprise a pressure venting system configured to maintain the pressure inside the pressure tolerant cavity within a range of pressures. The pressure tolerant cavity may be sealed to prevent water ingress.

A tetrafluoroethylene (TFE) copolymer film having a first endotherm between about 50 C. and about 300 C., a second endotherm between about 320 C. and about 350 C., and a third endotherm between about 350 C. and about 400 C. is provided. In exemplary embodiments, the third endotherm is approximately 380 C. In some embodiments, the second endotherm is between about 320 C. and about 330 C. or between about 330 C. and about 350 C. TFE copolymer films have a methane permeability less than about 20 g*micron/cm.sup.2/min. In addition, the dense articles have a void volume of less than about 20%. Methods for dense articles from core shell tetrafluoroethylene copolymers are also provided. The dense articles exhibit improved physical and mechanical properties such as adhesion and barrier properties.

A method of manufacturing a composite insert includes forming a polymer mold from a polymer sheet which may have a glass transition temperature of 70 to 160? C., the polymer mold either includes a cavity or may form a cavity disposed between the polymer mold and the carrier. The method proceeds by depositing a liquid reactive composite insert composition, which may be a two-component composition including a first part comprised of an isocyanate-epoxy blend and a second part comprised of an alcohol-epoxy blend, into the cavity under low pressure conditions of 0-10 bar and low temperature conditions of 15-100? C. The composition is then allowed to become dimensionally stable either within the polymer mold or between the polymer mold and the carrier.

Embodiments of the present invention are directed to a porous monolith polymeric composition having utility in catalysis, chromatography, filtration, and electro-kinetic pumps, devices incorporating such composition and methods or making and using such monoliths. The monoliths are characterized by a substantially homogeneous skeletal core with little shrinkage, few voids and few channels.

The present invention relates to a method for producing a PUR/PIR foam body, comprising the steps of providing a mold adapted for applying an underpressure to the interior of the mold; introducing a reaction mixture comprising an isocyanate-reactive component A and an isocyanate B into the mold, and applying an underpressure to the interior of the mold, so the underpressure acts on the introduced reaction mixture. The underpressure is applied to the interior of the mold no later than the reaction mixture has started to set in the mold, and the isocyanate index of the reaction mixture is 300.

A container includes a cup formed to include and interior region and an insulated sleeve. The insulated sleeve is coupled to an outer surface of the cup.

A foam composite with a skin formed in one shot by charging plastic powders or minute particles together with polyolefin pellets that can be cross-linked and foamed in a mold, and heating the mold while rotating. The composite absorbs almost no moisture, having satisfactory strength, being excellent as an insulating material. Further, providing a covering of a non-foaming or a slightly foaming material to the pellet of polyolefin that can be cross-linked and foamed, and conducting the forming, foamed granules as a core, and a covering of a reinforcing member for the core.
