Estimating the term…
The present invention provides a crosslinked polyolefin resin foam which is excellent in heat resistance, and also can be secondarily processed into a complicated shape. The crosslinked polyolefin resin foam includes a polyolefin resin composition containing 20 to 50% by weight of a polypropylene-based resin (A) which shows at least one endothermic peak measured by differential scanning calorimeter at a temperature of 160° C. or higher, 20 to 50% by weight of a polypropylene-based resin (B) which shows an endothermic peak measured by differential scanning calorimeter at a temperature of lower than 160° C., and 20 to 40% by weight of a polyethylene-based resin (c), and can be obtained by forming the polyolefin resin composition into an optional form and foaming and crosslinking the resin.
