A clever alternative – LIST Kneader is a unique solution for working in the concentrated phase

lndustry is under pressure to deve lop susta inab le processing methods. With this in mind, the List kn eader processor provides an alternative to the stirred-tank reactor for the production of po lymers, allowing so lven ts to be eliminated from the reac tion step. The kneader processor is also an alternative to the extruder for polymer devolatilization.

Apparatelücke geschlossen – Knetreaktor-Technologie vereint die Vorteile von klassischem Extruder und Rührkessel

In der Polymerhers tellung und -verarbeitung werden traditionell kontinuierlich arbeitende Rührkessel, Extruderschnecken und Dünnschichtapparate eingesetzt. Immer öfter kommen jedoch großvolumige, so genannte Knetreaktoren zum Einsatz. Die Bereitschaft zu fundamentalem Umdenken vorausgesetzt, verschaffen sie dem Betreiber Wettbewerbsvorteile.
