You can choose from a bench or floor model of the HAAKE PolyLab QC Modular Torque Rheometer. With an optional rack on the floor model, the instrument can be moved or even stored if needed. Based on the system’s backward compatibility, even existing measuring mixers and cq5dam.thumbnail.250.250 (3)extruders can be connected to the HAAKE PolyLab QC Modular Torque Rheometer. These devices are automatically recognized by the plug and play Thermo Scientific™ HAAKE™ PolySoft™ Software. This same software also identifies individual limits of the measuring systems, such as torque, speed and temperature and sets alarm values to minimize errors.

Characterization of PVC compounds

LR35-e. Torque-rheometers with laboratory mixers and laboratory extruders are down-scaled production machines, which enable the simulation of production processes in a lab environment. This measuring method allows testing and comparing materials close to production conditions.



Characterizing Powder Coatings in Oscillation

Application Note V-266. Differences in surface texture, that may arise from different curing kinetics and/or different visco-elastic properties, can lead to undesired creaking noises when the coated surfaces are strained. The method of choice to monitor curing processes rheologically is the oscillatory test.



Compounding of Carbon Nanotube (CNT) Suspensions with Polypropylene

The aim of the described test is to prove the feasibility of CNT-suspensions, as an option for safe handling of CNTs in a lab environment and for use with small scale twin screw compounders.




Comprehensive Material Characterization for Polymers

In the R&D Laboratory a new polymer is created by synthesizing small amounts of polymers or by blending existing raw materials to get the best performance for the final product.





Correlation Between Mixer Tests and the Extrusion Behaviour of PVC Dry Blends

LR60-e. This report describes the correlation between measurements done on a laboratory mixer with PVC Dry Blends and their processing behaviour on a counter-rotating twin screw extruder.




Curing of an Acrylate Glue – Rheology with Simultaneous FTIR Spectroscopy

Application Note V254. Using the Rheonaut module, the HAAKE MARS rheometer can be combined with an FTIR spectrometer to simultaneously record on the same sample what happens during the curing process and why it happens on a molecular level.




Degradation Tests – A new Test Procedure to Examine Polymers and Antioxidants with the HAAKE MiniLab

A simple procedure for the degradation test is given. It can work in the research lab as well as in a more rough production environment for QC purpose. With a minimal amount of material, tests can be run in real processing conditions.




Differentiating Polypropylene Samples from Different Suppliers with the Same MFR Value

LR19-e. This application report is based on a test done for a customer who was manufacturing biaxial stretched films and was using PP from two different suppliers.




Evaluating the Plasticization Process of Different Soft-PVC Samples

LR59-e. PolySoft Mixer data evaluation is explained in detail in this application note, and valuable hints are given for substituting PVC blend ingredients, e.g. plasticizers, stabilizers.
