DuPont™ Kapton® 250FN029 Polyimide/FEP Composite Film
Categories:	Polymer; Film; Thermoset; Polyimide, TS; Polyimide, Thermoset Film
Material Notes:	250 Gauge film structure consisting of a 50 µm (2 mil) base polyimide film with a 13 µm (0.5 mil) coating of Teflon® FEP on one side. Kapton® Type HN film coated with Teflon® FEP fluoropolymer resin, imparts heat sealability, provides a moisture barrier, and enhances chemical resistance. General Kapton® information: Kapton® is synthesized by polymerizing an aromatic dianhydride with an aromatic diamine. It has excellent chemical resistance; there are no known organic solvents for the film. It does not melt. It can be used at both high and low temperature extremes. Kapton® polyimide films can be used in a variety of electrical and electronic uses: wire and cable tapes, formed coil insulation, substrates for printed circuit boards, motor slot liners, magnet wire insulation, transformer and capacitor insulation, magnetic and pressure-sensitive tapes, and tubing.
