Insulation material for electric cables with superior flexibility and crosslinkability and electric cable produced with the same

摘要

An insulation material for electric cables includes an ethylene-alpha olefin copolymer with a melting point of 30 °C to 90 °C; and 0.5 to 20 parts by weight of a crosslinking agent based on 100 parts by weight of the ethylene-alpha olefin copolymer. The insulation material composition is based on a non-crystalline ethylene copolymer, and thus is flexible and satisfies tensile strength and insulation characteristics in conformity with the industrial standards. The insulation material composition is suitable for an insulation of electric cables for power, control and signaling that are installed in narrow spaces, in particular, electric cables for ships.
