FOAM MOLDED PRODUCT AND METHOD FOR PRODUCING THE SAME
Abstract:
The present invention is to provide a thermoplastic polyester elastomer resin foam molded product which exhibits light weight, excellent rebound resilience and excellent surface smoothness. A foam molded product including a continuous phase formed of a resin component containing a thermoplastic polyester elastomer, wherein the thermoplastic polyester elastomer is prepared by bonding a hard segment and a soft segment, wherein the hard segment consists of polyester constituted from aromatic dicarboxylic acid and aliphatic and/or alicyclic diol as constituting components, wherein the soft segment is at least one member selected from a group consisting of aliphatic polyether, aliphatic polyester and aliphatic polycarbonate, wherein the foam molded product is constituted from, as a surface layer ranging from a surface of the foam molded product to a depth of 1000 μm, a surface layer consisting of only a foamed region in which a non-foamed portion having a cell density of 10% or less is not present, or the foam molded product has, as a surface layer ranging from a surface of the foam molded product to a depth of 1000 μm, a surface layer consisting of both a foamed region in which the non-foamed portion is present and a foamed region in which the non-foamed portion is not present, and wherein the foam molded product has a density of 0.01 to 0.70 g/cm3.
