Abstract: A polyurethane urea fiber or film is made having high elongation, low modulus, low hysteresis loss, and excellent clastic recovery. The clastic polyurethane clastic fiber or film is formed from a copolymer glycol, a diisocyanate, a chain extender and optionally a chain terminator. The hard segment content of the polyurethane fibers is in the range of 8.0-13.0% by weight.
