Struggling with extrudate quality?

Learn about a potential source of degradation in extrusion systems


The flow path a polymer takes from the extruder to the die can have an impact on extrudate quality, especially for
polymers that are prone to degradation due to high temperature and or high residence time, such as PET and PC.

In this paper, you will learn about:

  • A background on polymer melt transfer systems
  • A comparison of elbow block design in melt transfer systems
  • Effects of elbow radius on velocity profile, shear rate and shear stress
