    Abstract: The shaped article consists ofa) 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, andb) 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.

    Abstract: The shaped body consists of a) 5 to 95 wt. % molding material A comprising at least one thermoplastic polyamide, copolyamide or a blend thereof as constituent A1, optionally filling and/or reinforcing substances as constituent A2, impact resistance modifiers as constituents A3 and other auxiliary and processing agents as constituent A4 and b) 5 to 95 wt. % of a molding material B comprising a thermoplastic polyamide, copolyamide or the blends thereof as constituent B1, at least one chained rubber-elastic polymer as constituent B2 and optionally other auxiliary and processing agents as constituent B3. The segment surfaces of molding materials A and B are joined to each in the shaped body. The inventive shaped bodies can be used in the automobile industry, e.g. as air or coolant ducts.
