Tecothane® thermoplastic polyurethanes (TPUs) are a family of medical-grade, aromatic, polyether-based TPUs available over a wide range of durometers, colors, and radiopacifiers. One can expect Tecothane resins to exhibit improved solvent resistance and biostability when compared with Tecoflex resins of equal durometers. As with any aromatic polyurethane, Tecothane resins tend to yellow upon aging or when subjected to radiation sterilization.
