Microstructure makes ePTFE a versatile medtech material

Expanded polytetrafluoroethylene (ePTFE) is a widely used material in medical devices with applications including vascular grafts and stent coatings. The material's versatility stems from its microstructure, which can be engineered in multiple forms to deliver varying properties such as chemical inertness, biocompatibility, flexibility, and durability. Understanding these structural variations is important for device engineers selecting ePTFE for specific applications.
