PURPOSE:To prepare the title foam excellent in the mechanical strengths, moldability, flexibility, heat resistance, etc., by foaming a resin compsn. comprising an ethylene-propylene copolymer, a high-density polyethylene, and a specific low-density polyethylene. CONSTITUTION:The title foam is prepd. by foaming a resin compsn. comprising an ethylene-propylene copolymer, a high-density polyethylene, and a linear low-density polyethylene obtd. by copolymerizing ethylene with a 6C or higher alpha-olefin (e.g. 4-methylpentene-1). |
