Title:
SHEATHED ELECTRIC WIRE AND CABLE
Document Type and Number:
WIPO Patent Application WO/2004/075213
Kind Code:
A1
Abstract:
A sheathed electric wire and a sheathed cable which comprise an electric wire or cable coated on the outermost layer with a polyethylene resin obtained through polymerization with a single-site catalyst. The polyethylene resin preferably has (i) a 50% crack initiation time (F50), which is a measure of stress cracking resistance, of 600 hours or longer, (ii) an abrasion wear as measured by the Taber abrasion test method of 10 mg or smaller, and (iii) an Izod impact strength (with notch) as measured at -40oC of 40 J/m2 or higher. This polyethylene resin may contain high-pressure low-density polyethylene. The sheath of the electric wire and cable is superior to the conventional polyethylene sheath in stress cracking resistance, abrasion resistance, and low-temperature impact resistance. The sheathed electric wire and cable are hence excellent in stress cracking resistance, abrasion resistance, and low-temperature impact resistance.
