55 Day(s) left to register

Wednesday Jun 12, 2024

Get started with reactive extrusion for your thermoplastics by getting a 360⁰ view of the process, reaction chemistry as well as how to configure the extruder.

In this simulated live course, Kenneth Russell will help you spend less time on trial and error & develop materials with reactive extrusion principles and practices faster by sharing hands-on tips on injecting liquids, defining the right residence time distribution (RTD)…

Why should you attend?

The environmental advantages of reactive extruder compared to the traditional reactors' present huge potential. Moreover, reactive extrusion can be used for a lot of reactions.

But do you have a structured methodology to determine the parameters for your thermoplastics’ reactive extrusion (right number of residues, the right temperature, the right screw speed…)? Are you clear on the effect of reaction chemistry on extruder? Without that you might end up doing trial-and-error & that can result in quality issues. This course will help you:

Save time by knowing the basics of reactive extrusion and how to achieve desired polymer properties using your extruder as a reactor

Understand the very important reaction chemistry (Free-Radical, Saponification and more...) governing the whole process

Achieve good mixing by understanding how to best configure the reactive extrusion process (Screw design, Liquid injection, Mixing configurations...)

Who should attend?

R&D Chemists, Research Engineers working with twin-screw extrusion
Product Development Manager
Compounders
Masterbatchers
Application Development Manager

who are willing to step into Reactive Extrusion. The course is particularly suited for people with prior experience in Twin Screw Extrusion

This course provided a quick but comprehensive overview of both the mechanical and chemical aspects that reactive extrusion entails. The course looked at both the engineering and processing side of reactive extrusion and extrusion in general, while also maintaining focus on the chemistry involved and how it can impact extrusion not only from a product quality viewpoint but also from a process safety view.

Jan M. , from Lehmann & Voss & Co. KG

It was useful to have a general overview of some key points/parameter in REX in twin screw. The Q&A was useful.

Joachim S. , from PolyOne

Learnt about possibilities of using a twin screw extruder as a reactor. Also, learnt about set up, start up and potential designs.
