CROSSLINKABLE FLAME-RETARDANT RESIN COMPOSITION, AND INSULATED ELECTRICAL WIRE AND WIRE HARNESS EACH OBTAINED WITH THE SAME

摘要

A crosslinkable flame-retardant resin composition excellent in flame retardancy, wearing resistance, flexibility, processability, and coordination to other materials. The composition comprises 100 parts by weight of a resin ingredient comprising (A) polyethylene having an MFR of 5 g/10 min or lower and a density of 0.90 g/cm<3> or higher and (B) a polymer selected among (B1) an alpha-olefin (co)polymer, (B2) an ethylene/vinyl ester copolymer, (B3) an ethylene/alpha,beta-unsaturated carboxylic acid alkyl ester copolymer, and (B4) a styrene elastomer, 30 to 250 parts by weight of (C) a metal hydrate, and 1 to 20 parts by weight of (D) a zinc compound, wherein the content of the ingredient (A) is 30 to 90 wt.%, the content of the ingredient (B) is 70 to 10 wt.%, and the ingredient (B) has been acid-modified and/or (E) an organic functional coupling agent is further contained in an amount of 0.3 to 10 parts by weight.
