Manufacturers create FEP (FN) polyimide film by coating polyimide film with fluoropolymer. This film performs similarly to FN Kapton and Apical Type AF. It is ideal for applications needing heat bondability or moisture and chemical resistance.
- Heat Bondable
- Excellent electrical properties
- High-Temperature Resistance

FEP POLYIMIDE FILM DETAILS
Polyimide FEP FN film, similar to Kapton® FN, results from coating Polyimide film with FEP fluorocarbon resin on one or both sides. Additionally, it offers excellent electrical properties, superior dimensional stability, and heat sealability. Thus, industries use Polyimide FEP FN film for insulation in motors, electrical apparatus, cable and magnet wire wrapping, and heater manufacturing, among other fields.

APPLICATIONS
WIRES AND CABLES
Apply fused FEP FN Kapton polyimide tapes to conductors and jackets for high-temperature wires. They offer excellent moisture and abrasion resistance, high dielectric strength, and maintain physical integrity after gamma radiation exposure. Use FEP as an adhesive binding agent in stationary applications. The wire can withstand 600°F for prolonged periods due to the bi-directional overlapping insulation design.
AUTOMOTIVE SWITCHES & DIAPHRAGMS
FEP FN polyimide film provides robust and sensitive diaphragms for various applications. For high temperature and high-pressure applications, stainless steel foil is an excellent option. However, for ultra-low flow control, the polyimide diaphragm is the best candidate. It has excellent sensitivity and low-flow capability. Use it in many automotive applications to monitor engine functions and auxiliary devices.
