Abstract:
1. A semiconductive composition, comprising, per 100 parts by weight of a polyolefin base resin: 0.5 to 2.15 parts by weight of carbon nanotubes; 1 to 10 parts by weight of a conductivity agent, the conductivity agent being carbon black, graphene, or a combination thereof; and 0.1 to 1 parts by weight of an organic peroxide crosslinking agent, wherein the semiconductive composition satisfies the following formula: wherein VR is a volume resistivity (Ωcm) measured at 90° C., CNT is weight % of the carbon nanotubes to the total weight of the semiconductive composition, and HS is a hot set value (%) measured according to IEC 811-2-1.
