Electrical Insulation Materials


Electrical Insulation Materials Offer Superior Quality and Reliability

These proven electrical insulation materials feature the right balance of properties, enabling them to deliver reliable performance even in the most demanding environments.

When you’re designing products that require electrical insulation systems (EIS), DuPont can make your job easier in meeting electrical insulation standards. That’s because we provide the industry’s broadest offering of pre-approved systems, over 400, by Underwriters Laboratories (UL) and recognized to IEC standards. These systems include a wide range of DuPont materials used in electrical insulation, including: films, aramid papers, pressboard products, and thermoplastic resins. Our portfolio of high-performance materials enable us to meet virtually all the electrical insulation requirements of today's transformers, motors, relays, switches, sensors and encapsulated coils and components.

Electrical Insulation Materials

  • Oasis® Composite Films

    Oasis® Composite Films

    DuPont™ Oasis® composite film is a family of heat sealable fluoropolymer-coated polyimide materials that are designed specifically to meet the demands of the aerospace and cable industry.


    • Oasis® 120TWT561

    DuPont™ Oasis® 120TWT561 is a heat sealable composite film that is made using DuPont high strength polyimide film and DuPont fluoropolymer designed to meet the light weight wire requirements.

    • Oasis® 200TRT515

    This film possesses excellent bonding characteristics to itself and to other fluoropolymer-containing materials, while providing low adhesion to metal conductors.
