What is this instrument for?
With the TwinLab-C 20/40, Brabender offers a stand-alone twin screw extruder especially designed for applications in a laboratory. It is used for product and recipe development,
feasibility studies in the context of process developments, material development, analysis of the process-dependent material behavior or developments in recycling.
Furthermore, it can be applied for raw material quality control, laboratory-scale production (e.g. sampling for customers) and compound preparation of test samples for mechanical or dynamic testing as well as for film cleanliness testing.
New compounds with or without additives or fillers, e.g. from thermoplastics, technical plastics, thermoplastic elastomers, ceramic materials or metal oxides, can be tested and developed on a laboratory scale.
What does this instrument measure?
■ Material temperature and pressure
■ Load / Torque
■ Viscosity (optional)
■ Residence time
Why is this important?
The measured values can be used to infer the relationship between extruder settings, process conditions and product properties. Due to the low throughput rates and the compact design of the machine, changes to extruder settings can be effected more quickly.
In general, the application of a laboratory extruder enables the development of new products, recipes and processes without impacting the ongoing production. Only a small amount of raw material is required for this kind of laboratory-scale process simulation. This
is particularly advantageous when expensive or poorly available material has to be tested. Likewise, only small amounts of product have to be disposed of.
