Thermosetting polyimide film has excellent thermal stability, chemical resistance and mechanical properties, high tensile strength and stable chemical properties. The application is also very wide

1. Application in winding electromagnetic wire.

The film is used as the substrate, and the perfluoroethylene propylene emulsion is coated on one or both sides to form an adhesive tape, which can be wrapped around the bare copper wire and then enter the high-temperature furnace. The film shrinks and the wire is tight, so that the wrapped The adhesive tape layers are melted into a whole, and when the wire is cooled out of the high-temperature furnace, add a pair of pressure rollers on both sides of the wire to improve the bonding strength between the adhesive tape layers.

2. Application in motor insulation.

Polyimide film can be used as insulation for high-power electric locomotives, alternators, anti-radiation motors and various precision motors.

3. The application of polyimide film in ribbon cables and flexible printed circuits.

Due to the softness of the film, good dimensional stability, and excellent dielectric properties, it is suitable for flexible printed circuits in the ribbon cable field. High-temperature chemical treatments such as corrosion and welding are suitable for microcircuits such as computers.

All in all, polyimide film is very widely used. In the field of electronic and electrical engineering, it is widely used as an insulating material in aerospace, nautical, general weapons, electromagnetic wires, cables, transformers, audio, microphones, mobile phones, computers, direct hair. Pliers and various motors. In addition, because the polyimide film layer has good mechanical ductility and tensile strength, it also helps to improve the adhesion between the polyimide layer and the polyimide layer and the metal layer deposited thereon.
