  • Compositions based on mixtures of ethylene-ethyl acrylate copolymers and ethylene-vinyl acetate-vinyl chloride terpolymers
    Patent number: 4648986
    Abstract: Compositions based on mixtures of ethylene-ethyl acrylate copolymers and ethylene-vinyl acetate-vinyl chloride terpolymers which have adhesion to and strippability from crosslinked olefin polymers. Compositions of this invention, which are rendered semi-conductive by the addition of carbon black thereto, are especially useful as outer layers bonded to layers of crosslinked olefin polymer insulation of electrical conductors.
    Type: Grant
    Filed: March 7, 1986
    Date of Patent: March 10, 1987
    Assignee: Union Carbide Corporation
    Inventors: Kunio Kotani, Akio Hayashi, Seiho Taniguchi

    Date of Patent: January 15, 1985
    Assignee: Union Carbide Corporation
    Inventors: Seiho Taniguchi, Yuichiro Sakuma
  • Flame retardant additives based on alumina trihydrate and ethylene polymer compositions, containing same, having improved flame retardant properties
    Patent number: 4430470
    Abstract: Flame retardant additive comprising alumina trihydrate and a methyl hydrogen polysiloxane which when added to ethylene polymers provide compositions which have improved flame retardant properties, have reduced gas evolution, do not drip or give off noxious gases on burning and are particularly useful as jacketing material about wire and cables.
    Type: Grant
    Filed: June 30, 1982
    Date of Patent: February 7, 1984
    Assignee: Nippon Unicar Company Ltd.
    Inventors: Seiho Taniguchi, Yuichiro Sakuma, Tadashi Yoshii
  • Polyolefin composition containing high molecular weight polyethylene glycol useful for electrical insulation
    Patent number: 4305849
    Abstract: A polyolefin composition for electrical insulation which comprises polyolefin or crosslinked polyolefin and a small quantity of high-molecular weight polyethylene glycol. This composition is far less vulnerable to the deterioration that occurs as dendroid voids when employed as an electrical insulation of high-tension power cables which are operated under water. The polyethylene glycol has more than 44 carbon atoms and is used in an amount from 0.3 to 10 wt % based on polyolefin.
