Magnetic sheet

Abstract

A magnetic sheet of the present invention comprises: 400 to 1,900 parts by weight of at least one kind of magnetic particles selected from the group consisting of magnetoplumbite-structure ferrite particles and rare-earth magnet particles, as a filler; and 100 parts by weight of a binder comprising 50 to 95% by weight of at least one thermoplastic elastomer selected from the group consisting of a styrene-isoprene-styrene block copolymer resin, a styrene-ethylene-butylene-styrene block copolymer resin and an ethylene-propylene copolymer rubber, and 5 to 50% by weight of at least one soft polyolefin selected from the group consisting of a propylene homopolymer and a propylene-ethylene copolymer. Such magnetic sheet is excellent in flexibility, mechanical properties, storage stability and product stability, and wherein the content of magnetic particles can be considerably enhanced notwithstanding the amounts of plasticizer and lubricant used therein are considerably minimized.
