A device for preparing a thermally conductive sheet with graphene fibers in an oriented arrangement includes a first mold and a second mold. The first mold is configured to press a first cuboid block, and the second mold is configured to repeatedly press the first cuboid block. The first mold is provided with a first mold groove. A first mold cover covers an opening end of the first mold groove, and the first mold cover and the first mold are configured to press the first cuboid block. A second mold groove is arranged on one side of the second mold, and a second mold cover is arranged at an opening end of the second mold groove. A movable thickness limiting block is arranged at a side of the second mold cover adjacent to the second mold groove, and is configured to be clamped in the second mold groove.

A refrigerator includes an inner liner, an outer wrapper and a trim breaker that extends between the inner liner and the outer wrapper to define an insulated structural cabinet. The trim breaker includes a plurality of gas-blocking flakes, wherein each gas-blocking flake includes a longitudinal axis that extends substantially parallel with an elongated surface of the respective gas-blocking flake. The longitudinal axis and the elongated surface of each corresponding gas-blocking flake is oriented to be substantially parallel with a portion of an outer surface of the trim breaker located near the respective gas-blocking flake.

The invention provides a molded article having excellent mechanical strength, heat resistance, surface roughness, and ferroelectricity. The molded article contains a crystal of a vinylidene fluoride/tetrafluoroethylene copolymer. The crystal is a crystal and is a nano-oriented crystal that has a size of 100 nm or smaller. The molded article has an arithmetic average roughness of 3.0 m or lower.

A plastic product having magnetic properties and a method for making the same is provided. The method comprises creating a mixture of a nylon and a metal, melting the mixture to create a melted mixture of the metal suspended in the nylon, injecting the melted mixture into a mold to harden the melted mixture and shape the melted mixture into the product's shape, applying an electrical current to the mold while the mixture is in a viscous state to align the poles of the metal suspended in the nylon in the mixture in a single direction before the mixture has hardened, and applying a magnetic field to the hardened mixture to provide the product with magnetic properties.

A film structure having a matte film surface and method of manufacture thereof. The preferred embodiment of the present invention contemplates a blend of polyethylene homopolymer or copolymer resins, coupled with one or more platelet shaped (non-spherical) inorganic or organic fillers. The matte polyethylene film surface as prepared from these polymer/filler blends exhibits a low gloss matte surface for wide utility in laminated and non-laminated, food and non-food, packaging and non-packaging applications. A unique and heretofore uncontemplated technique of manufacture exploiting the phenomenon of die swell as enumerated herein is utilized during production to facilitate the reorientation of the fillers during the extrusion process to produce the matte surface effect.

An elastomer molded body for a medical device includes an elastomer portion and a filler. The elastomer portion contains a crosslinked fluorine-based elastomer. The filler is formed from a plurality of particles each of which has aspect ratio of 5 or more and specific surface area of 3 m.sup.2/g or more and 10 m.sup.2/g or less. The aspect ratio is defined as a ratio of a dimension in a long axis direction thereof to a dimension in a short axis direction thereof. The filler has an uneven distribution in a surface layer part of the elastomer portion and is oriented in a direction along a surface of the elastomer molded body.
