<P>PROBLEM TO BE SOLVED: To provide a flame-retardant resin material having good operation efficiency by solving problems that terminal treating operation during carrying out wiring is not easily carried out though a resin composition prepared by compounding an inorganic flame retardant such as magnesium hydroxide in place of PVC as a nonpollution type flame-retardant resin composition without generating hydrogen halides having toxicity during combustion is used as a sheath layer or an insulating layer of electric wires/cables, etc. <P>SOLUTION: The flexible flame-retardant resin material is a flame-retardant resin composition composed of 100 pts.mass of a resin component containing at least one kind of an ethylene-α,β-unsaturated carboxylic acid ester copolymer, an ethylene-vinyl ester copolymer and an ultralow-density polyethylene, a flexible material and/or a liquid softener and a functional group-containing olefin polymer and 30-200 pts.mass of the inorganic flame retardant. The flexible flame-retardant resin material has ≤98 kJ/m<SP>2</SP>notched tensile impact strength and ≤150 MPa tensile modulus of a sheet material thereof. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
