Abstract
Draw a polymer composition by providing a polymer composition containing an orientable polymer having a softening temperature and a filler; conditioning the temperature of the polymer composition at or below its softening temperature; and drawing the polymer composition at a draw rate of at least 127 centimeters per minute in order to achieve an oriented filled polymer composition demonstrating a stable extent of cavitation with draw rate.
