INTRODUCTIONThe simple molecular configuration of polyethylene (PE)makes it prone to the development of strong molecularorientation when adequately processed. Some examples of processing techniques that can induce stronglevels of anisotropy in PE include hydrostatic extrusion and processes based on injection molding such ashigh-pressure injection molding, elongational flow injection molding,and shear-controlled orientation ininjection molding (SCORIM).
