HIGHLY FLAME-RETARDANT POLYMER COMPOSITION FOR ELECTRICAL WIRE AND ELECTRICAL WIRE PRODUCED THEREWITH

摘要

Provided are a flame-retardant insulation composition and an electrical wire produced therewith, which have an excellent balance between heat resistance, mechanical properties and flame retardancy. The flame-retardant insulation composition comprises 50 to 200 parts by weight of halogen-free inorganic flame retardant; 0.2 to 10 parts by weight of a lubricant; 0.2 to 10 parts by weight of a stabilizer, per 100 parts by weight of a base resin including 50 to 90 weight% of ethylene vinyl acetate copolymer singularly or a mixture of ethylene vinyl acetate copolymer and polarized poly olefin, and 10 to 50 weight% of modified polypheny lene oxide, wherein the modified polypheny lene oxide is a mixture including 10 to 50 weight% of polyphenylene oxide and 50 to 90 weight% of at least one rubber selected from the group consisting of high impact polystyrene and styrene-ethylene-butyrene-styrene (SEBS) rubber.
