FH polyimide F46 film for wire wrapping
FH polyimide F46 film is a kind of high performance composite material, which is coated with F46 on single side. Under high temperature as 350 degree, it will be self-adhesive. It is widely used as insulation material for electrical wire, electromagnetic wire, H class motors and other electrical applications.
Insulation, high temperature resistant, corrosion resistant
Magnetic wire, class H motor,
Insulation layer in product of magnet wire, cable, class H motor etc.
Available thickness: 38um 50um 60um
Introduction of F46 polyimide film
Polyimide F46 film type FH is made of polyimide film painted with F46 on single by dip-coating and sitering. The tape FH is suitable for wrapping electrical wire winding as class H insulation materials, which can be self-adhesive, fused and molding after half minute under temperature +350°.
F46 film we manufactured has outstanding performance as good heat resistance,thin & uniform insulation layer,good sealing etc.,which improves moisture resistance, electrical and anti cutting through performance of the wire.
Due to good flexibility of F46 film, no broken phenomenon occurs with insulation layer during wire's winding.So, it's suitable for winding motors class H and class F, and turn-to-turn insulation thickness is thinner about 1/3 than double wire enameled wire.
Besides above performance, F46 film also has good mechanical,electrical,fire resistant and radiation resistant properties.It is widely used in fields of aerospace, high-voltage motor,locomotive traction motor, deep well submersible pump motor,metallurgical motor etc.
