Torque Rheometer

HAAKE™ Rheomex OS Twin Screw Extruder: Small-Scale Compounding & Rheology


Optimize your material processing with HAAKE™ Rheomex OS Twin Screw Extruders, designed for the HAAKE™ PolyLab™ OS Torque Rheometer System. These modular extruders offer unparalleled flexibility for laboratory-scale compounding, rheological analysis, and process simulation. Choose between parallel or conical twin-screw configurations, seamlessly integrating with the HAAKE PolyLab Rheodrive OS via a plug-and-play connection. Ideal for R&D, formulation development, and small-scale production, these extruders require minimal sample sizes, saving valuable resources.

HAAKE™ Rheomex CTW 100 OS Conical Twin Screw Extruder:
The HAAKE™ Rheomex CTW 100 OS conical counter-rotating twin-screw extruder excels in high-shear compounding. Perfect for demanding applications like PVC compounding, wood fiber blends, and mixing polymers with varying viscosities. Its counter-rotating design ensures consistent material transport, high pressure and shear, and precise residence time control. Suitable for both laboratory and pilot plant settings, this extruder offers versatility with specialized screw geometries.

HAAKE™ Rheomex PTW 16 & PTW 24 Parallel Twin Screw Extruders:
The HAAKE™ Rheomex PTW 16 (16mm screw diameter) and PTW 24 (24mm screw diameter) parallel twin-screw extruders are designed for early-stage compounding and blending. Featuring a horizontally split barrel for easy viewing of melting and mixing processes, these extruders allow for customized screw configurations. Optimize performance with conveying, mixing, and kneading elements. The segmented top barrel facilitates modular integration of feeding and venting systems.

Applications:
  • Polymer Compounding
  • Rheology Testing
  • Processability Studies
  • Reactive Extrusion
  • Material Structure Analysis
  • Biopolymer Degradation Research
  • Screw Design Evaluation
