FEP FN Polyimide Film

Details

Polyimide FEP FN film (similar to Kapton® FN) is made of coating Polyimide film with FEP fluorocarbon resin on one side or double sides and and then it goes through a sintering process at high temperature. This combines the excellent properties of Polyimide film and FEP resin of high& low temp resistant, radiation resistant, corrosion resistant, excellent electrical properties, superior dimensional stability and heat sealable properties. It is widely used for insulation in motor, electrical apparatus and wrapping of cable and magnet wire, heater manufacture etc.

FEP FN Polyimide Applications

Wires and Cables

Fused FEP FN kapton polyimide tape are applied to conductors and jackets for high temperature wires. Excellent moisture and abrasion resistance, high dielectric strength, retains much physical integrity after gamma radiation. FEP is used as adhesive binding agent. In many stationary applications the wire can potentially withstand 600°F for prolonged time periods due to bi-directional overlapping insulation design.

Automotive Switches & Diaphragms

FEP FN polyimide film has the properties needed to provide a robust and sensitive diaphragm throughout a wide range of applications. Stainless steel foil remains a very good option for very high temperature and high pressure applications. However, for applications requiring ultra low flow control, the polyimide diaphragm is the most promising candidate. Polyimide diaphragms have excellent sensitivity and low-flow capability. It is used in many automotive applications for monitoring of engine functions and auxiliary devices.
