ELECTRICAL INSULATING RESIN MATERIAL, ELECTRICAL INSULATING MATERIAL, AND ELECTRIC WIRE AND CABLE USING THE SAME

摘要

An electrical insulating resin material characterized in that the rein component thereof which comprises an ethylene alpha -olefin copolymer satisfying specific parameters, such as 0.92 to 0.96 g/cm<3> in terms of density, 0.01 to 200 g/10 minutes in terms of MFR, 1.0 to 5.0 in terms of molecular weight distribution (Mw/Mn), and only one (peak) in terms of the number of peaks observed in an elution temperature-eluted amount curve as measured by the temperature raising elution fractionation (TREF) method, further comprises a monomer unit selected from among a carbonyl or carbonyl-derivative group-containing monomer, a hydroxyl group-containing monomer, a nitro group-containing monomer, an aromatic ring-containing monomer and a compound or monomer containing two or more ethylenic groups; an electrical insulating material and an electric wire and cable using the same. The electrical insulating resin material suitable for use in an electrical insulating material for an electric wire and cable, since it exhibits excellent processability without detriment to mechanical strength and shows excellent electrical insulating characteristics both before and after crosslinking.
