PTFE (Polytetrafluoroethylene) is a popular fiber choice for food and medical packaging, filtration media and much more.
PTFE (Polytetrafluoroethylene) is a fluorine-containing fiber characterized by its high chemical stability, moderate tensile strength, chemical inertness, and high melting point. The fiber can be drawn as a filament yarn called Teflon®, or it can be slit from a membrane and elongated resulting in ePTFE. PTFE has a very low frictional coefficient giving it a slippery hand.
Sample PTFE applications:
- Teflon® ribbon for lightweight and durable wildlife harnesses
- Release applications
- Self-lubricating bearings
- Packaging (food and medical)
- Filtration media for highly corrosive fluids
