Abstract: Fuel tank attachment, composed of a blend of a first plastic and a second plastic, wherein the first and second plastics are not miscible, wherein the blend contains a compatibilizer to render the first and second plastics miscible, wherein the first plastic is a fuel-resistant plastic, and wherein the second plastic is a non-fuel-resistant plastic, wherein the fuel tank attachment relates to a neck fitting, in particular, to a filler neck or a valve, in particular, a tank venting valve, or a cap element, wherein the fuel tank attachment is molded from a blend as one piece.

Abstract: The invention relates to a fuel tank accessory, consisting of a mixture of a first plastics material (A) and a second plastics material (B), wherein the first and the second plastics material are immiscible, wherein the mixture contains a compatibiliser for rendering the first and second plastics materials miscible, wherein the first plastics material is a fuel resistant plastics material and wherein the second plastics material is a non-fuel resistant plastics material. The fuel tank accessory is a spout, in particular a filler spout, or a valve, in particular a tank venting valve, or a cover element, wherein the fuel tank accessory is integrally moulded from the mixture.

Abstract: A composite part is produced by a process in which at least one of components a) and b) of said composite part is treated with an Openair plasma on a contact surface between said components a) and b) prior to production of the composite part, followed by molding-on of the other component; wherein said components are as follows: a) a part which entirely or to some extent comprises a molding composition comprising at least 40% by weight of a polyamide whose monomer units contain an average of at least 8 carbon atoms, and b) a part comprising another molding composition.
