Multi-Screw Compounding

Most materials today are compounded on multi- (usually twin-) screw compounding extruders. Most of these machines feature co-rotating, intermeshing screws, though there are applications in which counter-rotating, intermeshing or non-intermeshing machines are used. Extruders with more than two screws have been developed for applications requiring more intense devolatilization and reactive processing.
