PCTFE (Kel-F®)


PCTFE is the homopolymer polychlorotrifluoroethylene (Kel-F®). This fluoropolymer possesses a number of properties not usually found in other fluoropolymer resins, such as optical transparency, hardness, high compressive strength and an exceptional resistance to cold flow. Because it is a highly fluorinated resin, PCTFE is non-flammable and relatively unaffected by most corrosive chemicals. PCTFE maintains its excellent electrical insulating capability through thermal cycling and high humidity.

Note: Kel-F® is a registered tradename of 3M. In the 90’s, 3M discontinued production of Kel-F. Now PCTFE resin is manufactured by Daikin under the brandname Neoflon®.
