Bei der Coextrusion wird ein Extrudat aus mehr als einem thermoplastischen Schmelzestrom hergestellt. Es ist der Kunststoffextrusion sehr \u00e4hnlich, allerdings werden bei der Coextrusion mehrere Polymere in die Extrusionsd\u00fcsen eingef\u00fcllt, um ein einziges Profil mit einer Reihe von physikalischen Eigenschaften herzustellen.<\/p>\n\n\n\n

Einige Anforderungen des Marktes, insbesondere der Verpackungsindustrie, konnten nicht durch ein einzelnes Polymer erf\u00fcllt werden, obwohl sie durch eine Kombination von Polymeren erf\u00fcllt werden konnten. Die Coextrusion wurde erstmals bei der Herstellung von Gie\u00dffolien angewandt und wird heute auch bei der Blasfolien- und Plattenextrusion eingesetzt. In der Regel wird eine laminare Struktur angestrebt, bei der jede Schicht eine Schl\u00fcsseleigenschaft zur Gesamtleistung des Produkts beitr\u00e4gt. Coextrudierte Folien k\u00f6nnen sehr komplexe Strukturen sein, die aus vielen verschiedenen Funktionsschichten bestehen, einschlie\u00dflich Verbindungsschichten, deren Zweck es ist, benachbarte Schichten mit begrenzter Kompatibilit\u00e4t zu verbinden.<\/p>\n\n\n\n

Coextrusion is the process of forming an extrudate composed of more than one thermoplastic melt stream. It’s very similar to Plastic Extrusion,however, with co-extrusion you are inserting multiple polymers into the extrusion dies to produce a single profile with a range of physical characteristics.
