Zusammenfassung:PROBLEM TO BE SOLVED: To provide a crosslinked polyolefinic resin foamed article with surface hardness lower than ever before, and small shrinkage deformation at high temperature, suitable for making products such as automobile interior materials, ducts, floating buoyant materials, damping materials, heat insulation materials, packing, joint filling materials, buffer materials and washing sponge, through vacuum forming and stamping forming. SOLUTION: This crosslinked polyolefinic resin foamed article is formed by crosslinking and foaming a foamable resin composition obtained by blending a crosslinking agent and a foaming agent with a polyolefinic resin comprising a block copolymer having a melting point of 118-122°C measured by differential scanning calorimetry and a Shore A hardness of 59-86, and kneading the mixture.
