What is the Rheological Significance of the Entrance Pressure Drop?
Extensional Viscosity – Rheological Significance of the Entrance Pressure Drop Azadeh Farahanchi, Rheological Scientist, Ph.D Extensional/elongational viscosity measurements (melt strength) are of rheological importance in any plastic stretching process for example blow molding, sheet extrusion, blown film extrusion, fiber spinning, etc. as the plastic is constantly stretching or expanding in such processes. Two polymers […]
