1040mm Polyimide film for high temperature masking

High temperature polyimide tape for masking

Polyimide film is synthesized by polymerizing PMDA 4-formic acid-2-anhydride of benzene (PMDA )and 4.4-diamino-diphenyl-ether oxide (ODA) in strong polar solvents through the process of forming film and imine treatment at high temperature.

Polyimide film can resist high temperature and radiation as well as possess excellent dielectric performance and physical performance.

Polyimide film applicable to motor Grade H, electric appliance insulation, and the electric insulating materials for other purposes.

Appearance

Polyimide Film surface is smooth, bright and clean. It shall have no defects, such as folding, tearing, particulate, air bubble, pinhole and any external impurity. Its edges shall be orderly and have no breakage. And the film is provided in rolls.

Properties
Excellent flame retardant property
Excellent resistance to radiation

Excellent performance of insulation and mechanism

Good radio-resistance, irradiated with r ray of 10^9, its properties unchanged
High and low temperature resistant : -269C(-452.2F) ~+260C(+492F), wide range of working temperature –60C to +250C for long time, and up to +400C for short time working without any modification in electrical and mechanical properties
Excellent chemical stability. Resistant to freon and most organic solution, no corrosion made by any inorganic acid and alkali except for caustic alkali
Complexed with many materials, moisture protection and corroision resistance are greatly improved

Applications

Class H insulation for electric machinery and appliance

Formed coil insulation of traction motors etc
Slot liner insulation, interlayer insulation in Motor, transformer, capacitor insulation
For wrapping of electromagnetic wire and high-temperature cable

The substrates or overlay of Flexible Printed Circuits Board. (F-PCB)
The backing material for pressure –sensitive adhesive tape, F46(FEP) tape, polyimidetube
Nuclear industries
