ABSTRACT:
The advantages of a twin-screw extruder, especially the good plasticizing and homogenizing effect, are to be retained in the present invention with a simultaneous, above-average degassing output of the extruder. This object is achieved by dividing the twin-screw extruder into two stages (a) the plasticizing and homogenizing stage with a high screw torque and (b) the degassing and discharging stage in which a large, free degassing volume is achieved by a reduction in the screw core, by an enlargement of the screw housing and by adapting the screw diameter to the respective housing diameters in the degassing and discharging stage.
