Elucidation of mechanisms for stick slip melt fracture of polymer melt (Experimental analysis of unstable flow of high density polyethylene melt)
During polymer melt extrusion from a circular nozzle, the extrudate at low flow rate shows a stable linear shape with smooth surface but the extrudate at higher flow rate shows unstable shapes with spiral, rosary, or zig-zag structures. This phenomenon is known as melt fracture and hampers high thro...
