To provide a solid and up-to-date foundation of knowledge on the extrusion compounding of thermoplastic polymers. The main topics include fundamental concepts relating to the structure, properties, and processability of polymers, screw extruders (single-screw and co-rotating and counter-rotating twin-screw) and compounding lines. The main additives incorporated into polymer matrices will also be presented. Trainees will also have the opportunity to consolidate their knowledge through practical demonstration sessions using characterisation equipment (DSC and rheology) and extrusion compounding equipment (co-rotating twin-screw extruder).
