March 2010: What is your experience with Reactive Extrusion?
Significant process optimizations are foreseen with the Reactive Extrusion technology. Cleaner and shorter polymerization steps, added-value and functionalized polymers, easier blending are some of the most interesting outcomes of using Reactive Extrusion. And studies are still going on to identify further benefits. What is your own experience in using Reactive Extrusion? Are all these benefits true? Did you identify any side-effects or technical challenges ones should take care of to take all the good from reactive Extrusion, and only the good?
Challenges! - Mar 13, 2010

Benefit are real.
However, challenges are not spelt out in various papers. For example, problems in cleaning up the machine or the side reactions. Perhaps because that technology is what makes one company more competetive against another.
PU reactive extrution - Mar 18, 2010

I have worked with PU reactive extruder. The ingredients reacted inside and during the extrusion. It is a pain andneck operation.
But yes, it provides different type of benefits if the materials are right and you know how to do it. Nothing is easy. Do not believe what they said about the benefits. It has its own pros and cons. Nothing is general. It all need to be a special situation for secial case and for special purpose. Your end application and end performance may dictate the use of "reactive extrution" , if I know what it means..
