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 abc material as melt fracture and hampers high throughput production in polymer processin
