Members Reviews

The explanations about how to inject liquids and the proper screw design was useful.

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.

Robin van V. , from Kraton Polymers

This was a good introduction to reactive extrusion.
