PURPOSE:To provide a crosslinked olefin resin foam suppressed in a decrease in an elongation in a high-temperature region and excellent in heat resistance. CONSTITUTION:A crosslinked olefin resin foam prepared by molding a foamable resin composition comprising a polypropylene resin, a polyethylene of a density of 0.910-0.960, a thermally decomposable blowing agent and a crosslinking aid, irradiating the obtained molding with an ionizing radiation at a dose equal to or higher than the threshold value of crosslinking of polyethylene, and foaming the molding by heating. |
