<P>PROBLEM TO BE SOLVED: To provide a water-insoluble lignin; and to provide a molded product excellent in heat resistance, mechanical strength, coefficient of linear expansion, electrical insulating properties, and water resistance. <P>SOLUTION: A water-insoluble lignin of 230 μm or lower (excluding 0 μm) is obtained by pulverizing a lignin that is mainly of an H type. A molded product excellent in heat resistance, mechanical strength, coefficient of linear expansion, electrical insulating properties, and water resistance is obtained from the water-insoluble lignin and a thermosetting resin. <P>COPYRIGHT: (C)2013,JPO&INPIT |
