FEP
Fluorinated ethylene propylene (FEP) is fully fluorinated copolymer that has excellent chemical resistance in a wide range of temperatures and pressures, except for the melts of alkali metals, fluorine at high temperatures and fluorinating agents such as SIF3 and OF2.
Highly concentrated acids, alkalis and oxidizing agents do not cause swelling and changes in the strength properties of the copolymer. Diffusion of gases and liquids through the film of FEP is very low, less than the PTFE, it is also should be noted that it is insoluble in any of known solvents.
FEP is also remarkable for its good dielectric properties, which are low temperature- and frequency-dependant, high strength, it does not differ significantly from PTFE in mechanical properties, but is less cold-flow and has excellent weather resistance. The range of working temperatures is from -190 C to 205 C and can be easily transformed with the standard polymer-processing equipment.
FEP is used for lining products operating in particularly aggressive environments with high temperatures during the construction of reservoirs and tanks, which operate in the most extreme conditions.
