CROSSLINKED POLYOLEFIN FOAM

摘要

This crosslinked polyolefin foam is obtained by crosslinking and foaming a polyolefin resin composition containing: a polyolefin resin (A); and a rubber (B) with a Mooney viscosity (ML1+4, 100℃) of 15 to 85. This crosslinked polyolefin foam contains 10 to 150 parts by mass of the rubber (B) per 100 parts by mass of the polyolefin resin (A); the thickness of the foam is 1.5mm or more and has a 25% compressive hardness of 60kPa or less; the degree of crosslinking of at least one of the surface layer parts from either face to a depth of 500μm is at least 5% greater than the degree of crosslinking of the intermediate layer part excluding the surface layer parts on both surfaces.
