  • Resin composition, foamed resin using same, and electric wire insulated with foamed resin
    Patent number: 9115254
    Abstract: There is provided a resin composition for a foamed resin by generating bubbles, the resin composition made of a blend of a base resin and a polymer material other than the base resin, the polymer material dispersed in the base resin, in which: the bubbles are generated at circumference of the dispersed polymer material by infusing a foaming gas into the resin composition at a predetermined processing temperature; and melting point or glass transition temperature of the polymer material is between melting point of the base resin and the processing temperature.
    Type: Grant
    Filed: September 21, 2010
    Date of Patent: August 25, 2015
    Assignee: Hitachi Metals, Ltd.
    Inventors: Tatsuya Sasamura, Hideyuki Suzuki, Akinari Nakayama

  • FOAMED RESIN COMPOSITION AND WIRE/CABLE USING THE SAME
    Publication number: 20100200268
    Abstract: A foamed resin composition includes a polyolefin-based resin, and a ring opening polymer of norbornene or a copolymer of norbornene and ethylene or a mixture thereof. The ring opening polymer of norbornene or the copolymer of norbornene and ethylene or the mixture thereof is used as a foam nucleating agent in the foamed resin composition.
