<p><P>PROBLEM TO BE SOLVED: To provide a low-density polyamide resin composition for expansion molding, which has superior flexural properties, excellent expansion molding properties, and surface smoothness; and to provide a molded product. <P>SOLUTION: The polyamide resin composition for expansion molding includes a polyamide resin (A) and fibrous clay minerals (B). In the polyamide resin (A), the fibrous clay minerals (B) are dispersed in the form (I) or (II): (I) the fiber length of a monodispersed single fibrous crystal is 0.01-40μm and the maximum external dimension of agglomerates of monodispersed fibrous crystals is 0.01-40μm; and (II) the shortest distance between monodispersed fibrous crystals, the shortest distance between agglomerates of monodispersed fibrous crystals, and the shortest distance between a monodispersed single fiber crystal and an agglomerate of monodispersed fibrous crystals are each 1-100 nm. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
