Abstract

Official abstract text for this publication.

Provided are a foam molded product and a method of producing the same. The foam molded product is a molded product containing a resin and including a surface layer, a compressive deformation layer, and a foam layer. The thickness of the surface layer is 0.1 mm to 5.0 mm. The compressive deformation layer is located between the surface layer and the foam layer. Foam particles forming the compressive deformation layer have an average H/L of 0.5 or less (H: length in compression direction; L: length in perpendicular direction relative to compression direction). Foam particles forming the foam layer have an expansion ratio of not less than 3.0 times and less than 30 times.

First claim

Opening claim text (preview).

The invention claimed is: 1. A foam molded product containing a resin and comprising a surface layer, a compressive deformation layer, and a foam layer, wherein the surface layer has a thickness of 0.1 mm to 5.0 mm, the compressive deformation layer is located between the surface layer and the foam layer, foam particles forming the compressive deformation layer have an average H/L of 0.5 or less, where H is length in a compression direction and L is length in a perpendicular direction relative to the compression direction, foam particles forming the foam layer have an expansion ratio of not less than 3.0 times and less than 30 times, and an upper surface of the surface layer has an image clarity of 30% or more. 2. The foam molded product according to claim 1 , wherein the surface layer and the foam layer are formed of the same type of resin. 3. The foam molded product according to claim 1 , wherein the surface layer is provided with a textured shape. 4. The foam molded product according to claim 1 , used as an engine cover or an engine under cover. 5. The foam molded product according to claim 1 , wherein the resin is a crystalline resin having a melting point of 145° C. or higher or an amorphous resin having a glass-transition temperature of 145° C. or higher. 6. The foam molded product according to claim 1 , wherein the resin is a polyamide.
