Principle

Application of a shear rate range and measurement of the correspondent pressure drop from the barrel to the die to determine melt viscosity.


Capabilities

  • Melt viscosity in a wide range of shear rate (1 to 100,000 s-1)
  • Thermal stability tests
  • Evaluation of pressure profiles
  • Evaluation of the extrudate (color, flow instabilities, die swelling, die drool, …)
