<p><P>PROBLEM TO BE SOLVED: To provide a thermoplastic resin preliminary foamed particle that has an excellent rubbing sound proofness power, can produce a foamed particle molding excellent in mechanical strength, and in which the blocking is controlled, and the handleability is excellent, and to provide a thermoplastic resin foamed particle molding using the thermoplastic resin preliminary foamed particle. <P>SOLUTION: The thermoplastic resin preliminary foamed particle is characterized in that a 12-24C fatty acid amide, and the monoester compound of a 14-20C saturated fatty acid and glycerin adhere to the surface. The adhesion amount of the fatty acid amide is 1-8 pts.mass, and the adhesion amount of the monoester compound is 2-10 pts.mass based on 100 pts.mass of the preliminary foamed particle. Moreover, the thermoplastic resin preliminary foamed particle molding is obtained to mold the thermoplastic resin preliminary foamed particle in a mold, and the thermoplastic resin foamed particle molding 5 includes the in-mold molding body 55 of the thermoplastic resin foamed particle on at least a portion of the surface. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
