Tools for Ingeo Users: Optimizing for Industry Success

The Importance of Twin Screw Extrusion System Design When Processing Ingeo™ Polylactide

Success in polymer compounding is often defined by some combination of maximum rate, adequate dispersion of feedstocks, efficient devolatilization and recommended melt temperature. Just like any polymer, polylactide has its own physical and rheological properties that put constraints on these output criteria. Fortunately, the versatility of twin screw compounders provides an opportunity to adjust the process window to optimize the critical output variable for a specific end use application. This paper will discuss how proper system and screw design can improve both the extrudate quality and reduce the energy consumption without compromising output.

Don’t just take our word for it

I strongly recommend Innovation Takes Root. It's a good opportunity to understand and see what happens in this area of biopolymers. It's an international event and not just on PLA. I think it's well done, well-managed, and well-organized. It was a good investment for me.

I'd definitely come back (to ITR) and recommend it. I think many different industries could learn something from a conference like this - it really is focused on the next level of sustainability.

It has been a wonderful event; very well organized. I especially appreciate the scheduling of activities, the alternation of speeches, and time to network, which has been one of the key successes from my point of view. We also felt very supported by your team; we had the feeling you believe in what Flo is doing and, for us, that's very important.
