A cross-linked polyolefin resin foam of the present invention has a total light transmittance and a thickness that satisfy a predetermined condition, and has a reflection color difference Δ* of −10 to 16, a reflection color difference Δa* of −3 to 3, and a reflection color difference ΔL* of 50 or more. According to the present invention, there can be provided a cross-linked polyolefin resin foam that can suppress a change in color tone of transmitted light while ensuring transparency, and a pressure-sensitive adhesive tape, layered product, formed product, and display member that include such a cross-linked polyolefin resin foam.

Provided is a crosslinked polyolefin foam is made by crosslinking and foaming the composition, wherein a product of 25% compressive strength (kPa) and tensile strength (MPa) of the crosslinked polyolefin foam at normal temperature is 35 to 65.

Crosslinked polyolefin foam and molded body using same

The crosslinked polyolefin resin foam of the present invention is a crosslinked polyolefin resin foam obtained by crosslinking and foaming a polyolefin resin composition comprising a polypropylene resin and an olefin rubber; the olefin rubber having a Mooney viscosity (ML, 100&#xb0; C.) of 15 to 85; the olefin rubber being contained in an amount of 10 to 150 parts by mass relative to 100 parts by mass of the polypropylene resin; the foam having a 25% compressive hardness of 30 to 70 kPa and a compressive strength ratio, 25% compressive strength/5% compressive strength, of 2.0 to 4.5. According to the present invention, a crosslinked polyolefin resin foam from which a molded product excellent in appearance can be obtained even in a secondary processing to a complicated shape without impairment of flexibility, and a molded product made from the same are provided.
