Abstract

The shaped article consists of PA0 a) from 5 to 95% by weight of a molding composition A made from at least one thermoplastic polyamide, copolyamide or blends of these as component A1, fillers and/or reinforcing materials, if desired, as component A2, impact modifiers as component A3 and other additives and processing aids as component A4, and PA0 b) from 5 to 95% by weight of a molding composition B, made from at least one thermoplastic polyamide, copolyamide or blends of these as component B1, at least one crosslinked elastomeric polymer as component B2 and, if desired, other additives and processing aids as component B3, where, in the shaped article, segments of molding compositions A and B are connected to one another over a relatively large area. These shaped articles may be used in the motor vehicle sector, for example as air or coolant ducts.
