ePTFE (expanded polytetrafluoroethylene)

Expanded polytetrafluoroethylene (ePTFE) is a durable, flexible, and inert synthetic material made from expanded forms of PTFE, commonly known as Teflon. It features a microporous structure with tiny interconnected pores, making it both strong and breathable. ePTFE is used in medical applications like vascular grafts, patches, and filtration fabrics because it resists corrosion, is biocompatible, and allows fluids and gases to pass through while preventing blockages. Its unique properties enable it to mimic natural tissue behavior, making it valuable in situations requiring durable, biocompatible, and flexible materials.
