FEP
Known under the trade name Teflon®, FEP or fluorinated ethylene propylene is a fluoropolymer with remarkable properties. It is known for its almost perfect impermeability, good chemical stability and resistance to cryogenic temperatures.
FEP: what are its properties and advantages?
FEP is a polarized mixture of tetrafluoroethylene and hexafluoropropylene. Compared to some engineering plastics, this fluoropolymer is less resistant to wear, creep and tensile stress, but it has a high resistance to stress cracking. It also has good chemical inertness, a low dielectric constant, and a low coefficient of friction. It is less resistant to temperature extremes than FPA and PTFE, but can remain stable over a temperature range of -270°C to 240°C.
This thermoplastic is also known for its ability to resist and transmit UVC. It is therefore very popular for the decontamination of pathogens on objects in combination with ultraviolet lamps. Non-hygroscopic, with almost no moisture absorption, it is also used for the manufacture of pipes and fittings. It is also used to protect cables in aeronautics and to manufacture parts that must be perfectly watertight, such as joints.
