Abstract
Solid state draw a polymer billet, wherein at least 50 percent of all polymers in the billet is a continuous phase of polyethylene polymer having a density of 0.941-0.959 grams per cubic centimeter and a weight-average molecular weight that is 110,000 grams per mole or greater, at a drawing rate of 1.2 meters per minute or faster using a tensile force to create an oriented and cavitated polymer composition whose cross section dimensions all exceed two millimeters.
