     Product Description

    CEN® CR polyimide film

    CR polyimide film was developed specifically to withstand the damaging effects of "corona",which can cause ionization and eventual breakdown of an insulation material or system when the voltage stress reaches a critical level.

    CR polyimide film preserves the physical, mechanical property of polyimide film as it does, as well as the outstanding corona-resistant property, aiming at high power frequency control motor insulation.

    It is produced with adopting advanced dispersion technique which put the inorganic nano-particles into the film, so it can improve the performance of corona-resistant corrosion dramaticlly.
