    Abstract: The magnetic polymer filter material comprises 40-90 wt.% of polymer selected from polycarbonate, polyethylene, polypropylene, polyamide, polyester, teflon, polymethacrylate, polyacronitrile, polystyrene or polyethylene phthalate; and 1-60 wt.% of magnetic material selected from barium based ferrites, strontium based ferrites or lanthanum based rare earth metals. The magnetic polymer filter material is prepd. by mixing the polymer and the magnetic material; forming a sheet or mat form by spinning extruder; preparing the filter form by cutting; then magnetizing using by a magnetizer. The obtd. magnetic polymer filter material has 20-500 gauss of magnetic force, 0.1-20 mm of thickness, and 0.1-200 micro meter of pore size; and diameter of the polymer fiber in spinning is 0.1-2.0 mm. The magnetic polymer filter material has excellent filtering efficiency to an impurities contg. iron components, oxidized iron or metal dust.
