The Polyimide FEP Film is a dry adhesive tape, which is made by a polyimide film coated with Teflon FEP fluoropolymer adhesive on one side(FH) or both sides (FHF) upon high-temperature baking. Overall speaking, this film combines the excellent properties of Polyimide film and FEP(F46) resin, and it has a unique balance of excellent electrical, thermal durability, and chemical properties over a wide range of temperatures. It resists both high and low temperatures, radiation, and it is mechanically and electricallystable. In addition, it is self-adhesive. It also acts as a moisture barrier which enhances the chemical corrosion resistance.
Application
Electrical and Electronics, circuit board manufacture
H grade electric engine, transformer coil and capacitor insulation wrapping up in high-temperature, high-voltage condition
SMT thermal resistance, golden finger protection of PCB board
High temperature resistance and waterproof for electronic transformer, relay
Characters
* Higher mechanical strength, better dielectric strength with thinner insulation ply;
