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 […]


Twin Screw Course America and Europe 2015

After the success of the first Twin Screw Course (TSC) Europe, organized on the French Riviera, SCC is proud to announce two upcoming TSC: the TSC America 2015, located in UMass Lowell (Lowell, MA, USA) on October 7th and 8th and the TSC Europe 2015, located on the French Riviera, on December 2nd and 3rd, […]

Processing a PBT by twin screw extrusion : how to fix appropriate operating conditions by using numerical simulation

Processing a saturated polyester material This study has been performed by SCC with the support of Proplast, at the occasion of a specific workshop on twin screw extrusion issues, organized by Proplast, in Rivalta Scrivia (Italy). This practical shows the interest of using the numerical simulation for fixing appropriated operating conditions for processing a saturated polyester […]


Nanofillers: Optimization of the Processing Parameters for a Better Dispersion using 1D-Simulation

Nanoclay are nano-sized particles of layered mineral silicates. They are used as nanofillers to  mechanically reinforce  thermoplastic resins. The improvement of composite properties depends on the nanofillers dispersion  inside the polymer matrix which is reached by melt processing. Twin-screw extrusion, as traditionally used in industrial compounding, is the preferred method for processing thermoplastic/based composites. The objective of this […]

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 […]

PP Peroxide-Induced Degradation: predicting the material behaviour

Polypropylene (PP) when polymerized exhibits a high molecular weight (MW) and, consequently, high viscosity, which might be tricky for its processability. To improve this latter, MW can be tailored by different degradation methods. One of the most popular is the degradation of the PP induced by peroxide, because it is a straightforward and cost-effective approach. […]
