Research

The Institute of Polymer Processing looks back on 50 years of great achievements in the field of polymer processing. The institute addresses current research topics such as nanotechnology, waste utilization and energy savings.

 

Our goals

  • Understanding the processes
  • Systematic controlling of these processes for economic production of optimal products with minimum resources 
  • Development of a broad scientific understanding of the process basics 
  • Modelling and simulation
  • Verification on the equipment in our technical center

Our main research areas

Numerous successful national and international projects devoted to basic as well as applied research have generated a broad base of knowledge in different polymer processing techniques. The emphases are on:

Additive Manufacturing (3D -printing)

Summary

  • Material development: highly filled systems with metal or ceramic powders, modi-fied polyolefines
  • Process development: optimisation of process, characterisation of bonding, con-cepts for high qualitys


Compounding

Machinery and equipment

For an institute dealing with polymer processing, appropriate equipment and machin-ery are essential for training and project work. In the new laboratories, an exemplary and internationally renowned processing technology center has been set up, and thanks to our close cooperation with the polymer industry in Austria and Germany, it has been equipped with state-of-the-art machinery. Over the last few years, new ma-chines and systems worth more than € 1 million have been installed. In addition, we have a network of partner companies and partner institutes, where we can carry out experiments on various machinery. Thus, we are able to scale up from the smallest quantities to industrial production and produce from lot size 1 to thousands of pieces.
