Electrical Insulation

As an insulation material, the flex life of DuPont™ Kapton® and its ability to withstand extreme environments make it ideal for use in the motor and generator industry.

DuPont™ Kapton® CR and Kapton® FCR polyimide films for improved motor and generator performance. The unique properties of Kapton® allow it to be used extensively in the motor and magnet wire industry. In very thin sections, Kapton® conserves space for conductors, which ultimately yields more power and efficiency without increasing motor size.

DuPont Kapton® Polyimide Film Goes to Extremes in South Africa Few conditions are as severe as those encountered by South Africa's mining industry in the production of molten steel. To ensure uniform dispersion of impurities, "stirrer motors" are used in each continuous casting line as molten steel passes through the bore.

Kapton® insulation offers reliability in 24 hour motor operation Iscor’s steel billet mill motor in Newcastle, South Africa has to run under extremely arduous conditions.

Kapton® ensures extended functionality and longevity of Eurotran engines The winding wire primary insulation system hinges on FN type  Kapton® polyimide film by DuPont.

Kapton® improves operational flexibility in Alstom motors Kapton® polyimide film is the primary insulation for the magnet wires used in all the TGV motors since 1981.
