ABSTRACT:
A thermoplastic resin foam, which is high in thickness-direction compressive strength and low in flexural modulus of elasticity, can be set pliably along a curved applicable portion such as body's outer surface, and can effectively absorb an impact force imparted from the outside; and an expandable thermoplastic resin molded product providing the above foam. An expandable thermoplastic resin molded product comprises an expandable thermoplastic resin sheet-form material of expandable thermoplastic resin having a sheet body and many projections formed scattered on at least one surface of the sheet body, and an elastic thermoplastic material layer laminated on at least one surface of the expandable thermoplastic resin sheet-form material so as to be spread over the outer surfaces of the projections; and a thermoplastic resin foam obtained by foaming the expandable thermoplastic resin molded product.
