Abstract
There is provided a molded foam article including a foam obtained by foaming a formation material wherein the formation material contains a resin component, an Asker C hardness of the foam is 10 degrees or more, and a ratio E40/E0 of the foam is 0.5 or more, the ratio E40/E0 being a ratio of an elastic coefficient E40 at a strain of 40% in relation to an elastic coefficient E0 at a strain of 0% of the foam. The molded foam article has appropriate softness with a small change in hardness under compressive deformation.
Claims6
A molded foam article comprising:
- a foam obtained by foaming a formation material,
- wherein the formation material contains at least one resin component selected from a thermoplastic elastomer, a thermoplastic resin, and a rubber, and at least one selected from a vegetable oil and a mineral oil,
- an Asker C hardness of the foam is 10 degrees or more, and
- a ratio E40/E0 of the foam is 0.5 or more, the ratio E40/E0 being a ratio of an elastic coefficient E40 at a strain of 40% in relation to an elastic coefficient E0 at a strain of 0% of the foam.
