KEL-F® Characteristics
KEL-F® is a fluorocarbon-based polymer that is unique in the number of advantages it offers. This PolyChloroFluoroEthylene thermoplastic material can tolerate temperature extremes, is nonflammable, has good chemical resistance and near zero moisture absorption and has strong physical, mechanical and electrical properties.
KEL-F® has a use range of -400 to 400 degrees Fahrenheit and has extremely low outgassing which makes it an excellent choice for aerospace and semiconductor applications. Characteristics include:
Operating temperature range of -400° F to 400° F- Nonflammable
- Good chemical resistance
- Near zero moisture absorption
- Extremely low outgassing
Applications for KEL-F®
- Valves, seals and O-rings
- Food packaging film
- Fluid handling systems
- Sleeve and thrust bearings
