Polyimide Film Mica Tape

Description
Polyimide Film Backed Mica Tape, is mostly used for traction motor, a duplex laminate constructed of mica paper with aramid fibrid or muscovite mica paper bonded to polyimide film (e.g. Kapton) or corona resistant polyimide film with a high temperature silicone binder.
Corona Resistant Polyimide Film Mica Tape has excellent flexibility, high thermal resistance, good corona resistance, excellent physical and electrical properties after VPI treatment.

Application
Polyimide Film Mica Tape is widely used as a slot , an inter-turn, an inter-phase insulation for traction motor, transformer, and coils of class N (200°C).
