Abstract
The molding of the present invention has a continuous conducting path from an inner to an outer surface, comprising: A) a skin layer on the inner and outer surface of said molding, comprising an electrically conductive plastic molding composition A comprising a first base polymer; and B) a core disposed between the skin layer on the inner and outer layer of said molding comprising a plastic molding composition B comprising a second base polymer, wherein the molding composition A differs from the molding composition B. The molding may be a connector, for example a connector used in a fuel-line system for connecting plastic pipes and other assemblies.

A connector, comprising a wall which defines a cavity, said wall having an outer surface and an inner surface facing the cavity, wherein the wall comprises:
- A) a skin layer on the inner and outer surface of the wall, comprising an electrically conductive plastic molding composition A comprising a first base polymer and an electrically conductive additive;
- and
- B) a core layer disposed between the skin layer on the inner surface of the wall and the skin layer on the outer surface of the wall comprising a plastic molding composition B comprising a second base polymer,
- wherein the molding composition A differs from the molding composition B, and the skin layer on the inner and outer surface provide a continuously conductive path from the inner surface to the outer surface of the connector.
A reinforced molding, comprising a wall which defines a cavity, said wall having an outer surface and an inner surface facing the cavity, wherein the wall comprises:
- A) a skin layer on the inner and outer surface of said reinforced molding, comprising an electrically conductive plastic molding composition A comprising a first base polymer and an electrically conductive additive;
- and
- B) a core layer disposed between the skin layer on the inner surface of the wall and the skin layer on the outer surface of the wall comprising a plastic molding composition B which differs from molding composition A, and which comprises a second base polymer and at least one reinforcing material, wherein the skin layer on the inner and outer surface provide a continuously conductive path from the inner surface to the outer surface of the reinforced molding.
