Equipment in the plastics technology centre

With its state-of-the-art injection moulding machinery and extruders, the plastics technology centre is the place where new materials are being developed, and compounding and injection moulding of bio-based as well as conventional plastics and composites goes on. Besides application-oriented materials development, research is also focusing on the processing behaviour of these new materials and the relationships between material composition and processing behaviour.
