Molded part, which is a molded piece of laminated resin comprising, laminated in that order and firmly bonded together by thermal fusion bonding, (i) a layer of thermoplastic polymer (A), in which the thermoplastic polymer comprises at least a species selected from a styrene / butadiene based elastomer, a polyolefin based elastomer, a polyester based elastomer, a polyurethane based elastomer, a poly (vinyl chloride) based elastomer and an elastomer based of polyamide, (ii) a polyamide-based resin layer (B), in which the polyamide-based resin has an amine index, determined by titration of a solution of 1 g of resin in 50 ml of m- cresol with 1/10 N aqueous p-toluenesulfonic acid using thymol blue as an indicator, 10-60 (equivalent / 106 g), and (iii) a thermoplastic resin layer (C) in which the thermoplastic resin - contains a group functional that contains a carbo group nyl selected from carbonyl, carbonate, haloformyl, formyl, carboxyl, ester, acid anhydride [-C (> = O) O-C (> = O) -] and isocyanate groups, and - comprises a fluorine-containing ethylene polymer; said molded part can be obtained by a method comprising simultaneous coextrusion lamination of multiple layers using a coextrusion machine comprising a nozzle and a plurality of extruders each to feed a resin to said nozzle, in which the temperature of the nozzle is <= 230 ° C. |
