Capillary Rheometry Data Corrections for Polymer Processing Accuracy
Correcting raw capillary rheometry data for entry losses, shear gradients, and wall slip prevents costly tooling rework and protects gross margins.
Non Isothermal Flow Dynamics and Viscous Heat Generation in Polymer Melt Extrusion
Non-isothermal viscous dissipation drives core melt temperature spikes that cause extrudate defects if die land geometry is not scaled to shear rates.
Thermal Boundary Layer Instabilities and Viscoelastic Melt Degradation during High Throughput Molding
High throughput molding requires balancing injection velocity against viscous dissipation to prevent polymer chain scission and wall slip defects.
Rheological Variation and Thermal Thermal Equilibrium in Polymer Processing
Melt temperature drift over 3 degrees Celsius shifts shear viscosity past structural tolerances, requiring active thermal balance before line acceleration.
