  • Publication number: 20110217495
    Abstract: Moulded articles having reduced surface carbonization and longer retention of the mechanical properties and methods of producing same are presented. In an embodiment, the moulded article comprises polyamides with nanofillers, which can be produced by means of injection moulding or extrusion, in particular by extrusion blow moulding, coextrusion blow moulding or sequential blow moulding with and without 3D hose manipulation. For example, the polyamide moulding materials for the production of moulded articles have reduced surface carbonization in the moulded articles in subsequent long-term use at elevated temperatures.
