High Temperautre Insulation Polyimide PI Film

Descriptions:

High Temperautre Insulation Polyimide PI Film is a general-purpose film, synthesized by polymerizing an aromatic dianhydride and an aromatic diamine. It has excellent balance of electrical, mechanical, physical, thermal, and chemical properties over a wide range of temperatures from -269 to 400 (-452 to 752). It also has good dimensional stability, radiation resistance, and flame resistance. It does not melt or burn as it has the highest UL-94 flammability rating: V-0.


Features:

 • High dielectric strength

 • Good dimensional stability

 • Chemical resistance

 • Radiation resistance

 • Flame resistance UL V-0

 • UL approved qualified film

 • Temp resistance from -269℃ to 400℃ (-452℉ to 752℉)


Applications:

PI Film can be metallized, punched, formed, laminated, or adhesive coated. It can be used in a variety of electrical and electronic insulation applications:

• wire and cable tapes,motor slot liners, magnet wire insulation, formed coil insulation, transformer and capacitor insulation

• Polyimide Adhesive tape or polyimide laminates. .
• Coverlay or Stiffener in F-PCB
• Polyimide Label

• Polyimide tubing.

Process for producing Non Adhesive Polymide Insulation Film

Resin synthetise—-filter—cast—-imidization—rolling—inspection—-slitting—package

1)Resin synthetise

Synthetise PAA with 3 raw materials of PMDA ODA and DMAC after chemical reaction.

2)Filter
Bubble clearing in bubble clearing pan after filter. Second time filter after bubble is cleared.

3)Casting
Resin is casted on the belt through mould. Slicked resin is circled in hot wind in order to solvent evaporation and some imidization. The preliminary dry film (PAA film)  is conveyed to the front peel roll of casting machine and peeled off.

4)Imidization
Imidization process is heat imidization. Film peeled off from cast machine is imidized in imidization oven in high temperature. PAA film is transfromed into PI . In imidization, film is strengthed in CD, then the film is rolled.

5)Dry film temperature and machine speed.

 

Non Adhesive Polymide Insulation Film Slitting and Packaging

Film Roll Size: 3" paper or plastic core, film width: 6mm -520mm; standard width: 520mm, 1000mm

Die Cutting Services: We can cut the PI film into any size as your CAD drawing.

 

Transportation:

1)The film should be provided in rolls and wound up to the pipe core, each roll is well packed and loaded with plastic bag to be placed into dry and clean box.

2)The each box packing should be marked with the type, product specification, size, lot number, gross weight,date of manufacture, name of the manufacturer.

3)The should be pressured in dry and clean room, the preservation period from the date of production is 12 months and can still be used when it is qualified in case of the preservation period is exceeded and checked according to standard.

4)During the preservation and transportation, damping and mechanical damage should be avoided.
