Fall Polymer Insights Series Part 3 — Flow characterization:** PVC Extrusion and Capillary Rheology

  Summary

PVC processing behavior depends not only on formulation, but on how the material flows under the shear conditions encountered during extrusion.

In this practical technical webinar, Matthias Jährling, Senior Application Manager at Thermo Fisher Scientific, demonstrates how laboratory extrusion and capillary rheology can be used to characterize the flow behavior of PVC. The session covers extrusion fundamentals, the role of counter-rotating extruders in PVC processing, the principles behind capillary rheology, and a hands-on viscosity measurement using a laboratory extruder and slit capillary die.

Viewers will see how measurements at different extrusion speeds are used to generate shear rate, shear stress, and viscosity data; how reproducibility and measurement validity can be evaluated; and how corrected viscosity data can be used to better understand material behavior and support rheological modeling. The webinar connects practical laboratory measurements with decisions in PVC extrusion, formulation development, process optimization, and material characterization.

 

If you can't attend one or several sessions live, or if you want to review some concepts, the recordings will be available after each session.

  Who Should Attend?

The course is suitable for PVC and vinyl compounders, extrusion and process development engineers, polymer formulation scientists, rheologists, materials scientists, quality control teams, technical service teams, and laboratory professionals seeking to better understand PVC flow behavior and its relationship to extrusion processing.

  Why Should You Attend?

Understanding how PVC flows under processing conditions is critical to developing formulations and extrusion processes that perform consistently.

This webinar provides a practical look at how laboratory extrusion and capillary rheology can be combined to characterize PVC flow behavior under relevant shear conditions. Matthias Jährling demonstrates the measurement workflow from extrusion and sample preparation through pressure and output measurements, viscosity curve generation, reproducibility assessment, and data correction. Attendees will come away with a clearer understanding of how rheological data can help explain PVC processing behavior and support formulation development, process optimization, and modeling.

  At the end of this course, you will…

  • Understand the fundamentals of PVC extrusion and why extruder design and processing conditions matter for PVC dry blends.
  • Understand how capillary rheology can be used to characterize polymer flow behavior under extrusion-relevant shear conditions.
  • See how extrusion speed, pressure, and material output are used to calculate shear rate, shear stress, and viscosity.
  • Recognize shear-thinning behavior and understand how viscosity changes as shear rate increases.
  • Learn how measurement reproducibility and pressure behavior can be evaluated during a capillary rheology test.
  • Understand how corrected viscosity data and rheological models can support material characterization, process development, and simulation.
