Fluorinated Ethylene Propylene (FEP) is a resin coating that has a very high chemical and temperature resistance. Typically it is offered as an optional electrical cable coating on submersible pressure sensors where the liquid media is too aggressive for the more standard general purpose cable coatings.
FEP is highly inert and will withstand exposure to most chemicals and solvents such as Acetic acid, Acetone, Alcohols, Ammonia, Aromatic solvents, Beer, Chlorine, Citric acid, Detergents, Diesel, Fluorinated refrigerants, Fruit juices, Glycols, Hydrogen Peroxide, Hydrochloric acid, Nitric acid, Petrol, Gasoline, Kerosene and Sulphuric acid.
FEP has a high melting point and can be used in environments as high as 200°C (392°F). FEP also has a very high dielectric strength making it an excellent electrical insulator.
Since FEP coated sensors signal cables are more expensive than other polymer coatings such as PVC, it is only used when the application is too harsh for the standard cable types. FEP is often specified for liquid level measurements applications such landfill leachate monitoring, fuel tank level and chemical storage tanks.
