For inventory control purposes, product name may be followed  by an X.  Products labeled FEP 100 and FEP 100 X are equivalent, and all  information in this document is applicable to both. 

Typical Applications  

Wire and cable insulation, small tubing, and injection molded parts. 

Description  

Teflon™  FEP 100 is a melt-processible copolymer of  tetrafluoroethylene and hexafluoropropylene, without additives,  that meets the requirements of ASTM D 2116 Type I.

It offers the excellent combination of properties characteristic of  Teflon™  fluoroplastic resins: non-aging characteristics, chemical  inertness, exceptional dielectric properties, heat resistance,  toughness and flexibility, low coefficient of friction, non-stick  characteristics, negligible moisture absorption, low flammability,  performance at temperature extremes, and excellent weather  resistance. 

Teflon™  FEP 100 is a general-purpose grade and is used in many  different applications. It can be melt-extruded, and is used for  wire coating as primary insulation and, in certain cases, for cable  jacketing. Cables insulated with Teflon™  FEP 100 have met the  requirements of Underwriters Laboratory UL910 Steiner Tunnel  tests for installation in plenums without metal conduits.  

Stress-crack resistance is an important element in establishing  end-use performance. Extensive testing of wire and cable  constructions is needed for definitive performance evaluation. 

Experience shows that the MIT folding endurance or flex life  test, performed on a thin film of resin, has established a good  correlation with extensive cable testing. The higher the MIT  flex life, the higher the stress-crack resistance of the resin.  MIT test results should be viewed as a guide to comparative  performance of the various grades of resin. We recommend  that for applications involving repeated thermal and flex cycling,  specific tests on the final cable always should be undertaken.  See also the Chemours bulletin, “Grade Selector for Wire and  Cable Applications”.
