Kapton® FN

DuPont™ Kapton® FN is a general purpose HN film that is coated or laminated on one or both sides with
Teflon® FEP fluoropolymer. Kapton® FN imparts heat sealability, provides a moisture barrier, and enhances
chemical resistance.

Kapton® FN is recommended in applications that require a heat bondable film, or moisture and chemical
resistance beyond the capabilities of uncoated Kapton® films. Techniques for fabricating DuPont™ Teflon® FEP can be found in technical data bulletin H-55005-2. Chemical resistance data for Teflon® FEP can be found in information bulletin H-55007-2.
