Learn How To Remove Volatiles Via the Extrusion Process
April 29 to 30, 2025 Hyatt House Branchburg, Branchburg, NJ
It’s not a conference, it's a workshop!
Devolatilization (DV) is the process by which un-reacted monomer, solvent, water, dissolved gases, and/or other undesirable volatile contaminants are removed during the extrusion process from a polymer melt, due to deleterious effects the residuals may have on final product properties or because of tighter governmental or commercial standards.
Space is limited for this year’s event! We suggest you register ASAP. Previous workshops have sold out.
Leistritz Extrusion will host the 2025 Devolatilization Workshop, April 29 to 30 at The Hyatt House Branchburg and the Leistritz Process Development Laboratory in Branchburg, NJ. Classroom sessions will be held at Hyatt House Branchburg in Branchburg, NJ. Interactive extrusion demos will take place three miles away at the Leistritz Process Development Laboratory. Transportation will be provided to and from the demonstrations.
Lunch and handout materials will be provided on both days, as well as a dinner reception on the first day.
