Adhesives and Polymer Materials

The laboratory of adhesives and polymeric materials is engaged in the synthesis, formulation and characterization of plastics and adhesives and investigates and develops manufacturing processes for polymeric materials.

The development and characterization of plastics with specific requirements and the formulation of new, innovative adhesives with a special property profile are the main focus of the laboratory. In addition, damage analyses, ageing investigations and material optimisation are carried out using chemical, physical and mechanical methods. An extensive and universally usable, modern infrastructure is available for this purpose.
