ABSTRACT:
An open-cell cross-linked polyolefin foam possessing extremely high non-flammability is produced by dispersing a thermally expansible graphite in an adhesive agent and applying the resultant adhesive agent mixture to at least part of the surface of a flame-retardant open-cell cross-linked polyolefin foam. As the flame-retardant open-cell cross-linked polyolefin foam, an open-cell cross-linked polyolefin foam which possesses a polymer of a phosphorus type flame-retarding agent in the interior and the surface of the open-cell foam or an open-cell cross-linked polyolefin foam which contains a halogen type flame-retarding agent in the cell membranes thereof and possesses a polymer of a phosphorus type flame-retarding agent in the interior and the surface of the open-cell foam is preferably used.
