Title:
PHOSPHORUS-FREE NON-HALOGEN FIRE-RESISTANT INSULATED WIRE AND PHOSPHORUS-FREE NON-HALOGEN FIRE-RESISTANT CABLE
Document Type and Number:
Japanese Patent JP2015097210
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a phosphorus-free non-halogen fire-resistant insulated wire and a phosphorus-free non-halogen fire-resistant cable which have high fire resistance passing overseas fire resistance standards (EN, DIN and BS), are excellent in mechanical characteristics and show a smooth extrusion appearance.SOLUTION: A phosphorus-free non-halogen fire-resistant insulated wire has an insulation layer formed by coating the outer periphery of a conductor with a phosphorus-free non-halogen fire-resistant resin composition comprising 100 pts.wt. of a base polymer which is based on a copolymer of ethylene with a 3-8C α-olefin polymerized with a metallocene catalyst and contains 5-30 wt.% of an ethylene-vinyl acetate copolymer and 150-200 pts.wt. of a metal hydroxide mixed, and the insulation layer is crosslinked and has an elongation characteristic of 350% or greater, in a tensile test by JIS C3005.
