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.
