  FN Polyimide FEP Film

 

Description:

FN Polyimide FEP Film (e.g Kapton® FN Film, APICAL® Type AF, LIREN® FN) is a heat bondable film, made of polyimide film coated with FEP fluoropolymer adhesive on one side (FH) or both sides (FHF).

FN Film combines the excellent properties of Polyimide Film and FEP resin, imparts heat sealability, provides a moisture barrier, and enhances chemical resistance and has a unique balance of excellent electrical, mechanical, thermal, and flame resistant properties over a wide range of temperatures. The UL File No is E318791.

Characteristics

 • Excellent heat sealability

 • High Bond Strength

  High dielectric strength

 • Good dimensional stability

 • Chemical resistance

 • High Temperature resistance

 • UL approved qualified film

Application:

FN Polyimide FEP Film can be melted and formed soon as desired at defined temperature. It is widely used in heater circuits, heat sealable bags, and electrical insulation for electric motor, transformer, magnet wire and cable, coils and so on.
