Bionate® Thermoplastic Polycarbonate Urethane (TPU) is a thermoplastic elastomer with oxidative stability. These polymers are attractive in applications where oxidation is a potential mode of degradation, such as in electrostimulation leads, ventricular assist devices, and catheters. They are also extensively used in orthopedic applications for their tough, load bearing qualities.

Polyurethanes have been broadly used in the Medical Device Industry because of their combination of outstanding physical properties and in vivo biostability and biocompatibility. The product is currently available in various hardness grades including 80A, 90A, 55D, 65D and 75D. All grades are available with customizable Surface Modifying End Groups™ (SME).
