Thermoplastic Polyurethane (TPU) is a high strength, aromatic biomedical polymer with an impressive combination of mechanical properties and biological compatibility. With its excellent mechanical, puncture and abrasion properties, TPU is an ideal material for use in many medical device applications. Design engineers are increasingly choosing TPU for medical applications, thanks to the material’s desirable chemical properties, excellent mechanical characteristics and biocompatibility.
TPUs are widely used by orthopaedic device manufacturers to package hip, knee and spinal implants. Key features of TPU as a protective packaging material include;
While there are many grades of TPU to choose from, processing flexibility is a consistent feature of TPU regardless of which chemistry is selected. This provides medical device design engineers with numerous packaging alternatives as the TPU can be injection-moulded, thermoformed, die-cut, and welded into multiple shapes and sizes. The AQF Medical engineering team are available to assist customers with material selection and product packaging design .
