• Die Drool and Polymer Degradation 

      Hoy, Geoffrey S.; Giacomin, A. Jeffrey; Gilbert, Peter H. (2015-06-24)
      Die drool is an operational problem associated with polymer extrusion. Extrudate collects outside of the die, necessitating periodic disruptions for cleaning. There exists some debate as to the mechanism that produces ...
    • Slip Heating in Die Drool 

      Gilbert, Peter H.; Giacomin, A. Jeffrey (2014-05-14)
      When molten plastic is extruded from a die, it can collect on the open die face. Called die drool, this phenomenon costs plastics manufacturers by requiring shutdown for die cleaning. This has been attributed to cohesive ...
    • Slip Heating in Die Drool with Viscous Dissipation 

      Gilbert, Peter H.; Giacomin, A. Jeffrey (2014-10-06)
      Plastics can build-up on the die lip during extrusion. This phenomenon is called die drool and can be costly for plastics producers, requiring periodic shutdowns for die cleaning. Die drool has been attributed to the ...
