聚四氟乙烯廣泛應用於各種需要抗酸鹼和有機溶劑的場合，並被用來製作不沾鍋以及乾式變壓器。聚四氟乙烯質地柔軟，因此經常用於塗層 [註 1]。它剛被研究出來時的主要使用領域是高溫的發射火箭的內壁塗層。聚四氟乙烯也是止洩帶的主要成分。 性質 [編輯]

PTFE is a hydrophobic membrane that is chemically resistant to almost all solvents. It can be used with corrosive media, such as strong acids, alcohols, alkalis, and aromatics. The unit is readily available, allowing simple, fast and reliable HPLC or GC analysis of ultra-clean small-volume samples.

Inside the syringe filter polytetrafluoroethylene is used as membrane material. The hydrophobic PTFE membrane is very resistant towards all kinds of solvents as well as acids and bases. Flushing with alcohol, followed by water, makes the originally hyd

PTFE membranes are particularly suitable for preparing samples for HPLC analysis. The hydrophobic nature of the membrane also has applications for air and gas sterilization. The membrane is laminated onto a nonwoven polypropylene support web for improved strength and handling and can be used at temperatures up to 120ºC.
