Die Swell of Complex Polymeric Systems InTech

Die swell is a common phenomenon in polymer extrusion. When a viscoelastic fluid flows out of a die, the extrudate diameter is usually greater than the channel size. This is called dieswell, extrudate swell or the Barus effect. The degree of extrudate swell is usually expressed by the dieswell ratio (B) of extrudate diameter versus die diameter.
