  • Publication number: 20130001460
    Abstract: The present invention provides a urethane foam molded product that has high thermal conductivity with minimal change to its physical properties. A simple method for producing the same is also provided. The urethane foam molded product includes a base material formed of a polyurethane foam, and a thermal conductive filler mixed in the base material and oriented to form mutual connections. The thermal conductive filler is formed of composite particles that include thermal conductive particles formed of a nonmagnetic material, and magnetic particles adhered to the surfaces of the thermal conductive particles.

  • Publication number: 20090057603
    Abstract: A magnetic induction foam molding apparatus comprising: a pair of electromagnet parts, each of which has a core part composed of a ferromagnet and a coil part placed on the outer circumference surface of the core part, and that are placed so as to face each other and depart from each other with a predetermined distance in the axis direction of the core part; a foaming mold interposed between the pair of electromagnet parts, inside which a cavity is defined; and a yoke part connecting back surfaces of the respective core parts of the pair of the electromagnet pats so as to form a magnetic path between a pair of the back surfaces. In the cavity of the foaming mold, a uniform magnetic field is formed.
