HAAKE* CTW 100 QC for the HAAKE PolyLab* QC system

Twin-screw laboratory extruders have a proven record in continuous compounding with feed-dosing of different additives (liquid or solid) along the extruder barrel. The combination of a twin-screw extruder unit with additional sensors offers the ability to measure material properties of the melt during processing.

The twin screw extruder with intermeshing counter-rotating screws provides a positive material displacement from the hopper to the die and thus high levels of pressure. Because of its conical design the twin screw compounder HAAKE Rheomex CTW 100 QC realizes very short dwell times and avoids dead volumes. Applications such as processing of thermal critical compounds, development of new PVC compounds, mixing in processing additives, blending of polymers with different viscosity are usually supported with this extruder.
