Abstract
A multilayer molded article having a body of a thermoplastic resin and a skin material which is laminated on a surface of said body and made of an olefin thermoplastic elastomer having 100% modulus (M100) at 23.degree. C. of from 20 to 60 kg/cm.sup.2 and a frictional resistance (tan .delta.) against a metal surface of 1.0 or lower which is backed with a foam layer, which has good appearance and also good weather resistance.
Claims4
A multilayer molded article comprising a body of a thermoplastic resin and a skin material which is laminated on a surface of said body, the skin material comprises an olefin thermoplastic elastomer having 100% modulus (M100) at 23.degree. C. of from 20 to 60 kg/cm.sup.2 and a frictional resistance (tan .delta.) against a metal surface of 1.0 or lower, the skin material is backed with a polyolefin foam layer.
A method for producing a multilayer molded article which comprises placing, between unclosed male and female molds, a skin material, the skin material comprising an olefin thermoplastic elastomer having 100% modulus (M100) at 23.degree. C. of from 20 to 60 kg/cm.sup.2 and a frictional resistance (tan .delta.) against a metal surface of 1.0 or lower, the skin material is backed with a polyolefin foam layer, supplying a thermoplastic resin melt between said polyolefin foam layer and either of said male and female molds, and closing said male and female molds to integrally bond said skin material and said thermoplastic resin.
