摘要

Described is a process for preparing shaped bodies, optionally structural and/or thermoinsulating, having an ennobled outer surface, said process comprising the steps of: a) extruding a tube of thermoplastic polymer; b) placing the extruded tube into a blow-molding mold composed of two half-molds; c) inserting an ennobling film compatible with the thermoplastic polymer between the extruded tube and at least one of said two half-molds; and d) molding the tube.
