| 摘要 |
The foamed laminate based on olefin according to the present invention is composed of a substrate layer of a foamed body made of either an ethylenic thermoplastic elastomer comprising a polyethylene resin and an ethylene/alpha-olefin copolymer having a Mooney viscosity ML1+4 (100° C.) of 90-250 and an ethylene content of 70-95 mole % or an ethylenic thermoplastic elastomer composition comprising 100 parts by weight of an olefinic thermoplastic elastomer and 1-20 parts by weight of an olefinic thermoplastic resin and, under lamination thereon, a skin layer made of either an ultrahigh molecular weight polyolefin resin having an intrinsic viscosity of 3.5-8.3 dl/g or made of an olefinic thermoplastic elastomer composition comprising an olefinic thermoplastic elastomer and a lubricant. The foamed laminate according to the present invention is easy in recycled use, obtainable at a high foaming expansion ratio with soft hand touch and is superior in the appearance, abrasion resistance, durability and sliding performance.
