<p>A multilayer thermoplastic composite comprising at least one layer made from a polyamide-based moulding composition, at least one layer made of a polyester-based moulding composition and an adhesion promoter between the two layers is disclosed. The adhesion promoter comprises a polyamide, a polyester or a mixture thereof. The composite combines the good rigidity, excellent barrier action and high temperature resistance of polyesters with the good mechanical properties of polyamides. The composites of the invention are useful fox manufacturing structural components, for example in electrical, machine and automotive industries. They may also be used as films, in particular as foodstuff packaging films, or as multilayer tubes.</p> |
