Application of twin screw extruders for reactive processing

Abstract

Reactive extrusion has grown in a few years from a specialized technique for creating experimental materials to the preferred production technique for manufacture of standard polymer systems (ex. polyurethanes) and modification of these systems (ex. grafting). The complexity of the extruder system design has also grown tremendously. The ability of reactive extrusion to produce a myriad of products in a single piece of capital equipment makes it attractive to R&D, manufacturing and financial groups.
