Scale-up challenge in reactive extrusion and compounding processes: 1D numerical simulation as a powerful tool

Reactive extrusion … is more and more used for compounding high performance polymers which have complex formulations that imply potential compatibilization issues. Therefore, using twin-screw extruder (TSE) as a continuous reactor in which chemical reactions facilitating the compatibilization is a solution. The main issue could turn up when passing from a well-controlled formulation at lab scale […]

Predicting the reaction rate in a twin screw extruder

Twin screw extruders (TSEs) are widely used in chemical polymer modification or polymerization. Indeed, TSEs are continuous chemical reactors proposing an important mixing capability, even with highly viscous polymers. Their flexibility in the screw design and control of temperature is an asset for processing chemical reaction as they allow to control and favor residence time […]
