polymer processing instabilities understanding and t is less severe than melt fracture but still affects product aesthetics. Mechanism: This instability is caused by a combination of surface shear stress and the viscoelastic nature of the polymer. When the shear stress at the die exit surpasses a critical thresh O Ophelia O'Conner Sep 22, 2025
