FHF polyimide F46 film is taking polyimide film as substrate material, and coating with F46 on its double sides. FHF polyimide F46 film has outstanding properties as high temperature resistant, radiation resistant, corrosion resistant etc like polyimide film.
Double sides be adhesive at high temperature
Magnetic wire, class H motor,
Insulation layer in product of magnet wire, cable, class H motor etc.
Available thickness:50um, 60um
Descriptin and application of polyimide F46 film:
In the wrapping electromagnetic wire, and the perfluoroethylene propylene（F46） emulsion is coated on one side or double side to make polyimide F46 composite film.
F46 PI film can be wrapped around the bare copper wire, after entering the furnace high temperature (about 350 ℃), the film due to shrinkage and wire wrapped tightly, the sticky layer melt into a whole.
Features: good heat resistance, thin and uniform insulation layer, and good sealing. It improves moisture resistance, electrical performance and anti pass performance of wire. Due to the good flexibility of thin film, the insulation layer is intact and no rupture occurs when the conductor is bent. It is suitable for H and F motor winding resistance. The thickness of the interturn insulation is about 1/3 thinner than that of the double wire enameled wire, and the thermal conductivity is good, the volume of the motor is reduced and the reliability of the motor is improved. It is widely used in spaceship, high voltage motor, locomotive traction motor, deep well submersible pump motor and metallurgical motor and so on
Tips: (Features of polyimide film):
Polyimide film is high temperature resistant, chemically stable, fire retarding,. Typical polyimides are anti-chemical solvents such as hydrocarbons, esters, ethers, alcohols and chlorofluoroalkanes. They are also resistant to weak acids but are not recommended for use in more concentrated alkaline and inorganic acids environments.
