The flexible substrate is typically used to make a flexible display or a flexible electronic.Type: ApplicationFiled: July 26, 2006Publication date: January 31, 2008Inventors: Robert L.

Patent number: 6841583Abstract: A composition that has an ethylene/?-olefin copolymer (A), a blowing agent (B), and optionally, an organic peroxide and a crosslinking assistant. The ethylene/?-olefin copolymer (A) has an ethylene/?-olefin copolymer (A1) having a density of not less than 0.880 g/cm3 and less than 0.900 g/cm3 and MFR (190° C.) of 0.1 to 50 g/10 min and an ethylene/?-olefin copolymer (A2) having a density of 0.900 to 0.930 g/cm3, MFR (190° C.) of 0.1 to 50 g/10 min and a main melting point peak at a position of not higher than 110° C., in a specific ratio. A foamed product, obtained by heat treatment of the composition, may be further subjected to secondary compression. A laminate made of the foamed product and a layer made of a polyolefin, a polyurethane, a rubber, a leather or an artificial leather. Footwear or a footwear part made of the foamed product or the laminate.Type: GrantFiled: August 15, 2002Date of Patent: January 11, 2005Assignee: Mitsui Chemicals, Inc.Inventors: Takanori Sueda, Masayoshi Yamaguchi, Atsushi Komoriya, Kouichi Kizu
