  • Patent number: 6716923
    Abstract: The invention provides an olefin resin composition for powder molding comprising 100 parts by weight of an olefin resin (A) having a glass transition temperature of 25° C. or lower such as a propylene homopolymer or hydrogenated styrene-butadiene block copolymer and 0.5 to 30 parts by weight of a non-halogen type thermoplastic resin (B) such as methyl methacrylate having a glass transition temperature of 60 to 200° C., an average particle diameter of 0.1 to 10 &mgr;m and a sphericity of 0.8 to 1.0. The resin composition is very excellent in powder flowability and can be easily molten even under conditions where there is little or no pressure or shear stress action, and so best suited for use as powder slush molding compositions.

  • Patent number: 6294257
    Abstract: An electrically conductive elastomer film comprising (i) a thermoplastic elastomer and (ii) 5 to 100 parts by weight, based on 100 parts by weight of the thermoplastic elastomer, of an electrically conductive filler, and having a volume resistance of 0.1 to 5 &OHgr;cm as measured in the direction perpendicular to the film plane. This film is produced by a casting process wherein a releasable base is coated with a solution prepared by dissolving or dispersing 5 to 30 parts by weight of the sum of a thermoplastic elastomer and an electrically conductive filler in 100 parts by weight of an organic solvent; the thus-formed coating is dried; and then the thus-formed film is released from the releasable base.

  • Patent number: 5826721
    Abstract: A foldable container for storing and transporting rolled articles wound on a spool or a support tube, comprising a top cover, a bottom panel fixed to the bottom frame, front and rear partition panels, and left and right panels. The front and rear panels are each divided into upper and lower parts along division lines, and formed therein with support holes aligned with the division lines and opposed between the front and rear partition panels. The two halves of each of the support holes are covered at their inner peripheries with elastic protectors, and opposite end parts of the support tubes are received in the support holes so as to suspend the rolled articles between the partition panels. Thereby it is possible to surely store the rolled articles with less time and labor, and to reduce consumption of packing material to a minimum value with no damage thereto being caused even though primary packing is eliminated.

  • Patent number: 5709053
    Abstract: A panel for constituting sound insulating wall is provided with a front plate, a rear plate, and a sound absorbing member put between the plates. The sound absorbing member contains reduced plastic products coated with magnetic material such as magnetic tape and magnetic sheet. The front plate is provided on the sound source side and constituted of a plate having numerous holes. The sound absorbing member is composed of a permeable bag and the reduced plastic products in the bag so that the bulk specific gravity and permeation resistance can be 0.05-0.4 and 3-90 dyn.S/cm.sup.4, respectively. The reduced plastic products may be reduced plastic products alone not subjected to other processings, or may be a mixture of reduced plastic products and molded bodies of reduced plastic products. Alternatively, only molded bodies of reduced plastic products can be put in the permeable bag.
