Nowadays, the medical polymer materials might have a lot of side effect. Based on the superior biocompatibility and stable chemical properties, TPU can be used for the artificial heart and heart assist devices, medical catheters (infusion tube, central venous catheter), artificial blood vessel, orthopedic bandage, artificial limb, contraception product, medical adhesive, dressing, drug controlled-release carrier, contact lenses, medical artificial skin and etc. TPU has become the most promising green environmental protection material in 21st century.

TPU has perfect flexibility and ductility. Therefore, according to the customers’ demand, it can be adopted injection or extrusion molding in the process of manufacturing. In addition, it feels very comfortable not like other materials with great viscosity. At present, Lubrizol is the main medical TPU manufacturer.

TPU has good characteristics such as well toughness, solvent resistance, hydrolysis resistance, microbe resistance, abrasion resistance, anti- bending, easy processing and controllability. All of these advantages ensure that in vivo or vitro polyurethane products can take effect. Thus, TPU will be promising as a new generation of medical high polymer material in the long run.
