FLAME RETARDANT RESIN COMPOSITION AND INSULATED ELECTRIC WIRE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a flame retardant resin that can produce a non-halogen flame retardant insulated electric wire without pre-heating a conductor before extrusion processing and an insulated electric wire using the flame retardant resin.

SOLUTION: The flame retardant resin composition comprises (A) 30-60 wt% straight chain ultra low density polyethylene having a density of 0.880-0.908 g/cm3and a melt flow rate (MFR) of 0.5-4.0 g/10 min, (B) 40-70 wt% ethylene/vinyl acetate copolymer (EVA) or ethylene/ethyl acetate copolymer (EEA) having a comonomer content of 12-25 wt% and a melt flow rate (MFR) of 0.1-5.0 g/10 min and (C) as a flame retardant, a magnesium hydroxide added in an amount of 80-160 pts.wt. per 100 pts.wt. the resins (A+B). The insulated electric wire is produced by using the resin composition.
