Polytetrafluoroethylene (PTFE) is a completely fluorinated thermoplastic. It has a range of operating temperature covering K208F to C4308C (K29Degree C to C212 Degree C). The temperature range is based on the mechanical and physical properties of PTFE. When working with aggressive chemicals, it may be essential to reduce the limit of upper temperature. PTFE has excellent corrosion resistance properties, and it is almost inert in the proximity of most materials. A very few chemicals may attack PTFE at normal temperatures.
Primary sodium removes fluorine from molecule, and other alkali metals like lithium, potassium, etc. act in the same way. Fluorine and other allied compounds are absorbed into PTFE resin, to a degree that the blend becomes sensitive to an ignition source. These strong oxidizers should be handled with care. Handling of 80% sodium hydroxide, ammonia, aluminum chloride, and certain amines at high temperatures have same effect as of elementary sodium.
