Flammhemmende Harzzusammensetzung und deren Verwendung

摘要

A flame-retardant resin composition that has an excellent cold-resistance property and wear-resistance property even when containing as a flame retardant a metallic hydrate such as magnesium hydroxide, and an insulated wire including the composition. The resin composition contains a flame retardant mainly consisting of a metallic hydrate, and a base resin, wherein the base resin contains two or more kinds of polyolefin resins having a flexural modulus of 2000 MPa or more, wherein at least one of the polyolefin resins has a melt flow rate (MFR) of 5 g/10 min or less. The base resin preferably further contains a polyolefin resin having a melt flow rate (MFR) of more than 5 g/10 min. At least one of the polyolefin resins is preferably a polypropylene resin having a functional group. The insulated wire includes a conductor, and an insulator containing the flame-retardant resin composition, with which the conductor is covered.
