polyimide film

Polyimide Films & Tapes

Polyimide film and polyimide tape meet high performance cable and wire insulation needs with their reliability, durability and combination of outstanding electrical, thermal, chemical and mechanical properties.

Polyimide film and tape offer unique high and low operating temperature capabilities, plus high abrasion and cut-through resistance. They can operate at 220 degrees Celsius and provide dielectric values at 5,000 volts per mil. Chemical properties include resistance to most acids, solvents, lubricants and hydrocarbons, while electrical properties include high dielectric strength and low dissipation factor. By offering an extensive range of polyimide film and polyimide tape, you can be certain we'll be able to meet your unique design and process requirements.

Apical Polyimide Film

APICAL polyimide film possesses an excellent balance of physical, thermal, electrical and chemical properties over a wide range of temperature (-269°C [-452°F] to 400°C [752°F]). More precise thickness control, superior web flatness, plus improved adhesion and excellent dimensional stability are standard features with Apical polyimide films.
