<P>PROBLEM TO BE SOLVED: To provide an automotive trim that consists of a foamed particle-molding body that can show excellent mechanical properties and high expansion ratio, the foamed particle-molding body comprising a polypropylene-based resin, while using a mixed resin of a polypropylene resin and a polylactic resin as a base resin. <P>SOLUTION: The automotive trim comprises the foamed particle-molding body, wherein the molding body comprises the polypropylene-based resin and has a density of 0.1 g/cm3, and a disperse phase comprising the polylactic resin is dispersed in a continuous phase comprising the polypropylene resin. The polypropylene-based resin configuring the foamed particle-molding body comprises, at predetermined blending ratios: a polylactic acid resin; the polypropylene resin; and an ethylenic copolymer that has a thermoplastic elastomer and/or an epoxy group. In a cell membrane cross section of the foamed particle-molding body, the number of disperse phase having a greatest dimension of 8 μm or larger accounts for 4% or lower including 0 of the total number of the disperse phase. The rate of dimensional change in the foamed particle-molding body at 80°C is within ±3.5%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
