What is FEP?
FEP stands for fluorinated ethylene propylene, which is a copolymer of tetrafluoroethylene and hexafluoropropylene.
What are the properties of FEP?
FEP has outstanding electrical properties, UV resistance, and is chemically inert to a wide range of industrial chemicals and solvents. It also has a low coefficient of friction, stress crack resistance, and can withstand temperatures ranging from -400°F to +392°F.
What are some common uses of FEP?
FEP is widely used for fluid handling and chemical processing equipment, pump housings and pipe linings, semiconductor wet bench equipment, food processing and packaging equipment, and medical components.
What are the performance characteristics of FEP?
FEP is chemically inert to industrial chemicals and solvents, has good electrical properties, a low coefficient of friction, stress crack resistance, and outdoor weathering resistance.
What is the elongation at break for FEP?
The elongation at break for FEP is 300 - 325%.
How does FEP compare to PTFE?
FEP is similar to PTFE in that it is a soft material with low tensile strength and low wear resistance. They are also similar in their electrical properties, chemical inertness, strength, moisture absorption, and anti-stick characteristics.
What are some specific applications of FEP?
FEP is commonly used for wire covering, FEP spaghetti tubing, FEP linings for pipes in the chemical industry, aircraft wiring, and glazing for solar energy collectors.
What are some advantages of using FEP?
Some advantages of using FEP include its resistance to heat, wear, and chemicals, as well as its flexibility and excellent electrical properties.
What are some limitations of FEP?
Some limitations of FEP include its lower heat resistance compared to TFE, higher coefficient of friction, and poorer wear resistance.
