PROBLEM TO BE SOLVED: To provide a crosslinked polyolefin-based resin foam which is excellent in heat resistance, mechanical strength and flexibility and gives a molding of a desired shape with a good appearance. SOLUTION: The crosslinked polyolefin-based resin foam is obtained by crosslinking and expanding a resin composition which comprises 100 pts.wt. polyolefin-based resin consisting of 40-80 wt.% polypropylene resin and 20-60 wt.% polyethylene-based resin and 1-10 pts.wt. hydrogenated block copolymer whose block portion at the both ends is a polymer block of a vinyl aromatic compound and whose block portion in the middle is a polymer block of a conjugated diene compound. The resin foam has excellent heat resistance, mechanical strength and flexibility. COPYRIGHT: (C)2005,JPO&NCIPI
