<P>PROBLEM TO BE SOLVED: To provide a urethane foam molded body having desired sound absorbing characteristics as well as high heat releasing characteristics, and a method for producing the same. <P>SOLUTION: The urethane foam molded body comprises a base material comprising polyurethane foam, a magnetic filler blended in the base material and oriented adjacently to each other, and a low melting alloy powder blended in the base material and comprising an alloy having 50-150°C melting point. The method for producing the urethane foam molded body comprises a process for preparing a mixed material by mixing a raw material for the foamed urethane resin, the magnetic filler and the low melting alloy powder having 50-150°C melting point, and a foam molding process for foam molding the mixed material in a magnetic field having almost uniform magnetic flux density by injecting the mixed material in the cavity of a foaming mold. <P>COPYRIGHT: (C)2010,JPO&INPIT |
