Multi-screw extruders – an overview

Abstract

Screw extrusion is a cost-effective and solvent-free method for manufacturing polymer blends and composites. This article reviews the latest developments in the field of multi-screw extruders, i.e. triple-screw, quad-screw, octa-screw, ring, planetary and multi-rotation system (MRS). The authors also discussed limitations and directions of multi-screw extruders development.
