Abstract:
PURPOSE:To improve surface flexibility, by using a thermoplastic elastomer as the molding material of a skin layer. CONSTITUTION:A sheet or film 4 made of a thermoplastic elastomer composed of a blend body consisting of a polyolefinic resin and a partial crosslinked substance of ethylene/alpha-olefin copolymer rubber is preheated to be sucked to the inner wall surface of the cavity 3 of molds 1, 2 so as to be closely brought into contact therewith and, after clamping, a synthetic resin in a flowable plasticized state is injected in the cavity 3 to fill the same and molded. By this method, a molded body excellent in flexibility, scratch resistance, damage resistance and cold resistance and reduced in temp. dependence of flexibility and having no surface stickiness can be obtained.
