Articles such as melt spun elastic tape and heaving denier monofilament fibers are made from thermoplastic polyurethane (TPU) polymers. The process to make the articles involves using a substantially horizontal cooling to cool the melt spun articles. Preferably, the cooling is accomplished by a water bath. A crosslinking agent is added to the TPU polymer melt to enhance the elastic properties of the articles.
