Twin-Screw Extrusion and Applications

As discussed in Chapter 5, the second-largest extrusion process is twin-screw extrusion, mainly used for the preparation and processing of complex polymeric materials, through compounding and reactive extrusion. In this chapter, after introducing the different twin-screw extrusion processes, we will focus on the corotating twin-screw extruder for which the main aspects will be detailed, and we will review a number of applications ranging from polymer blends or filled polymers to reactive extrusion.
