  • Publication number: 20190153208
    Abstract: Provided is an insulating resin composition that contains a resin component containing a first copolymer which is a copolymer of ethylene and an unsaturated hydrocarbon having 4 or more carbon atoms, a second copolymer which is a copolymer of ethylene and an unsaturated hydrocarbon having 4 or more carbon atoms, which is subjected to acid modification, and which has a density of less than 0.88 g/cm3, and a third copolymer which is a copolymer of ethylene and an acrylic acid ester or the like, in which a ratio of contents of the first to third copolymers is within a specific range, and 30 to 100 parts by mass of a flame retardant and 1 to 5 parts by mass of a crosslinking assistant relative to 100 parts by mass of the resin component.

  • Publication number: 20180294073
    Abstract: Provided is an insulated electric wire that mainly contains a polyolefin resin, has excellent flexibility, heat life, and waterproofness, and is used in wiring of vehicles such as automobiles, and an insulating resin composition used in forming an insulating layer of this insulated electric wire. The insulating resin composition contains a first copolymer, which is a copolymer of ethylene and an unsaturated hydrocarbon having 4 or more carbon atoms and which has a density less than 0.88 g/cm3, a second copolymer which is a copolymer of ethylene and an acrylic acid ester or a methacrylic acid ester, a flame retardant, and a crosslinking aid. Also provided is a crosslinked body having a 2% secant modulus of 35 MPa or less at room temperature and an elastic modulus of 2 MPa or more at 150° C.
