Laboratory Process for FEP resin
Melt processable copolymers of TFE and HFP are usually known as FEP (fluorinated ethylene propylene copolymers). As perfluorinated thermoplastic polymers, they have unique end-use properties like chemical resistance, weather resistance, low flammability, thermal stability, and outstanding electrical properties. FEP resins can be easily molded into coated wires, tubes, pipes, foils and films. A synthetic process for this polymer was developed at IICT in collaboration with Hindustan Fluorocarbons Ltd for Vikram Sarabhai Space Center, ISRO for cryogenic plumbing application. However, because of its unique properties, many other applications are also possible. Its melt processing can provide coatings with superb chemical resistance, release properties, low coefficient of friction and resistance to wetting by both oil and water. Because of these properties, FEP is widely used in food processing and chemical industries.
