REACTIVE COMPOUNDING | PROCESSING
these products could be used as chemical building blocks to manufacture PLA-based hot melt adhe- sives by reactive extrusion. One of the key tools used for reactive
extrusion work at the AIMPLAS technical centre is a ThermoFish- er Scientific HAAKE MiniLab II Micro Compounder, which is said to be very well suited to reactive extrusion optimisation processes at laboratory scale. The HAAKE equip- ment allows polymer synthesis to be examined by means of controlled reactive extrusion processes at laboratory scale (it is also used for compounding of expensive or small-scale materials such as nano- composites, bio-polymers or pharmaceuticals). AIMPLAS also has a dedicated pilot plant for scaling-up reactive extrusion processes from the laboratory level to batches of several kilograms. This comprises a ZSE 27 MAXX twin screw extruder from Leistritz that was specifically designed for the reactive extrusion process with a high 56 LD ratio screw and barrel. The pilot plant is completed with an extensive variety of gravimetric feeders and

pumps to handle liquid monomers. Downstream equipment includes water bath and strand pel- letiser as well as an underwater pelletiser. One of the challenges in the development of
reactive compounding processes is the need for the combination of a first-hand understanding of both polymer processing and chemistry. That is a combination of skills that is not present in all companies, according to Dr Björn Bergmann, Group Leader Compounding/Extrusion at Fraun- hofer Institute for Chemical Technology-ICT.
