Polyimide Film | For High Temperature Masking

Product Description

Polyimide film is synthesized by polymerizing PMDA 4-formic acid-2-anhydride of benzene (PMDA )and 4.4-diamino-diphenyl-e-ther oxide (ODA) in strong polar solvents through the process of forming film and imine treatment at high temperature.It can resist high temperature and radiation as well as possess excellent dielectric performance and physical performance.

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
