In many processes, you will find that the polymer not only is exposed to deformation due to shear, but also due to elongational deformation. It is well established that the measured elongation of a polymer allows characterization of its structural properties. Our instruments simulate a wide spectrum of elongational deformation, as for example found in the blown- and flat-film extrusion process, or in fiber spinning..


Tensile testing - instruments for simulation of high deformation taking place in the most different processes.

The technical Test-System to determine the extensional properties of Polymers.
The test device measures the extensional properties of polymer melts by drawing a vertical melt strand at a constant pull-off speed or with a linear or exponentially accelerating velocity. It measures also the force needed to elongate the strand, and calculates elongational stress, draw ratios, rate of elongation and elongational viscosity.
Spin Line Rheometer
Spinning tests at process related conditions.
The D-Melt is a standardized melt elasticity tester, combined with a melt index measurement


This is a compact unit designed to cool, blow, wind up and draw out the extruded tubes. Alternative uses from those described above, for a film-blowing machine, include the production of small film tubes with varying thicknesses, and for applications mostly found in the food or packaging industry where a smaller size as we offer, is often a better fit compared to the use of large-scale extruders.
This is a compact machine that combines the cooling, winding and take-off of flat films made from PP, PE and other types of plastics. In addition, it produces small films that have variable thicknesses that are used in the packaging industry and more specifically in the food industry where the use of large film production units does not provide the same efficiency.
