Process and lab twin-screw extruders and compounders.

Small, simple, and scalable

Achieve reliable scale-up, reduced time to market, and controlled, continuous processing using Thermo Scientific compounders and extruders. Our twin-screw compounders offer flexible compounding configurations for small batches for either pilot scale production or low volume manufacturing and are well-suited for research and development in the polymer, pharmaceutical, bioscience, and nanotechnology sectors. Pharmaceutical manufacturers rely on our twin-screw extruders to create uniform material blends for the preparation of various dosage forms for low solubility APIs. Our instruments cater to a broad range of process requirements for even the most challenging drug formulations.

Torque Rheometer

A torque rheometer is a  measuring mixer or extruder system used in quality control (QC) and research and development (R&D) for materials such as polymers, rubber, ceramic mixtures or food. Torque rheometers deliver information about melting behavior, influence of additives on processability, temperature or shear stability, and rheological characterization, e.g., injection molding. 

The advantage of modular torque rheometers is that an interchangeable mixer, single-screw extruder, or conical and parallel twin-screw extruder can be connected to maximize flexibility for daily measuring needs.

Small samples are suitable for micro compounding

Micro-compounders are suitable for  early material development when only a few grams of sample available for testing . For example, 5 grams is sufficient with a micro-compounder.

All micro-compounder models are equipped with a back-flow channel and a bypass valve which allow control of the residence time of the sample in the compounder. Depending on the compounder model, it is also possible to measure the relative sample viscosity at different screw speeds. When combined with a mini injection molding machine, scientists can produce specimens for further analysis from limited sample amounts.

Compounder Accessories

We offer  a broad range of  up- and down-stream equipment to complete the compounding process. Accessories such as pelletizers, wire coating, blow-molding, film take off and chill rolls, as well as a range of dies and feeding systems are available.

‘Green tires’ that you can actually make

There’s a lot of choice in tire ingredients – natural rubber vs synthetics, silica, carbon black types, reinforcing fibers, compounding agents, etc.  Your next eco-friendly ‘green’ tire has to be one you can also manufacture on the production line.

By simulating a full-scale processing environment in the test lab with a modular torque rheometer and extruder system, you can test the processability of various rubber compounds. View this free application note showing how such a system was used to test rubber compound with different types of carbon black.
