Your point of contact for polymers

In accordance with the core competencies of the Montanuniversität Leoben, the Department of Polymer Engineering and Science integrates all necessary special fields along the value chain “from the material to the final product”. They range from chemistry of polymeric materials via material science and testing of polymers, the designing of plastics and composite materials, the polymer processing to the application of plastic components and recycling. Consequently, the research topics addressed by the department are equally wide-ranging.
