Compounding

Our primary focus is on the compounding of post-production or post-consumer plastics. Additionally, we engage in R&D and pilot trials for new sustainable innovations. As a result, our compounding line is frequently used to simulate (thermal) mechanical recycling of thermoplastics as well as extrusion trials. For this purpose, we utilise the Krauss-Maffei Berstorff ZE25 UTX extruder.

The Krauss-Maffei Berstorff ZE25 UTX is a 25mm co-rotating twin-screw extruder. This type of extruder is typically used for lab and pilot-scale compounding. With a variety of conveying, kneading, and mixing elements available, the screw configuration can be optimised for a specific formulation. Additionally, the extruder can be equipped with melt filtration and vacuum degassing. The extruder features a gravimetric feeding system with a side feeder.

The twin-screw extruder can be employed for various purposes, including:

• Formulation development
• Process development
• Testing the impact of additives
• Pilot-scale production of compounds
• Recycling of waste streams
• Removal of non-melting contaminants via melt filtration
