Nomex® Electrical Insulation

Nomex® Paper, An Original Benchmark for Performance, Reliability

DuPont™ Nomex® is a brand that has earned the trust of manufacturers around the world by delivering superior quality and proven reliability for a wide range of electrical insulation applications.

For nearly 50 years, Nomex® has been the material of choice for electrical insulation, helping to extend the life of electrical equipment and prevent premature failures. 

Within the Nomex® family of products—primarily Nomex® paper and pressboard in various forms—there’s a high-quality material to address virtually any electrical insulation requirement.

By using Nomex® paper as electrical insulation, manufacturers of everything from transformers and generators to wind turbine systems and hybrid electric vehicles (HEV) have been able to help improve the integrity and performance of their own products.

Nomex® paper has played a key role in positioning DuPont as a global leader in electrical insulation systems which are used in electrical equipment covered by applicable UL, IEC   and country specific standards such as IEEE and JL. 

With a continuing focus on technical innovation, DuPont is working closely with engineers throughout the electrical industry as they develop new and modified products using Nomex® that will help them meet the evolving electrical insulation needs of the future.

DUPONT PRODUCTS & SERVICES

  • Nomex® 410 and the 400 Series

    Nomex® 410, an original benchmark product, is widely used for a majority of electrical equipment applications and is considered our gold standard based on its more than 50 years of proven performance. It anchors the Nomex® 400 Series.

  • Nomex® 400 Series and Nomex® 410 - DuPont™ Nomex® Insulation

    Nomex® 800 Series

  • Nomex® 900 Series - DuPont™ Nomex® Insulation

    Nomex® 900 Series

  • Nomex® 300 Series

    Nomex® 300 Series is a family of insulation products based on the same technologies as Nomex® 410 but with less mechanical and electrical strength. These products provide good value-in-use for applications where Nomex® 410 is “slightly” overdesigned .

  • Crepe Paper made with Nomex®

    From automatic and manual wrapping of transformer and motor leads to continuous transposed cable wrap, insulating crepe paper made with Nomex® is an ideal choice for applications requiring a high degree of conformability and elasticity.

  • Laminates made with Nomex®

    DuPont works with highly qualified laminators who produce high-quality laminate insulation products based on Nomex® paper to address a broad range of performance requirements. Nomex® is the critical component that helps enable these laminates to perform.
