    • Thermal Class H (220°C): Handles prolonged high-temperature exposure
    • High Dielectric Strength: Delivers reliable insulation for motors and electrical systems
    • Tear & Puncture Resistant: Retains structure under physical stress
    • Flexible & Conformable: Ideal for wrapping, slot liners, and interlayer insulation
    • Chemical & Moisture Resistant: Maintains performance in harsh environments

    Applications:

    • Electric motor insulation in rewind and repair projects
    • Dry-type transformers and power distribution systems
    • Slot liners, phase insulation, and coil wrapping
    • Layer and barrier insulation in industrial equipment

    Availability:

    • Standard thicknesses: 0.05 mm to 0.76 mm
    • Supplied in rolls or sheet format
    • Custom sizes and slit widths available upon request
    • Roll width: 914 mm

    Nomex® 410 is part of our flexible laminate insulation range. For a complete insulation solution, consider pairing it with our high-temp sleeving or electrical varnishes and resins.

    Nomex® 410 vs NMN / NPN – Which Insulation Should You Choose?

    Nomex® 410 and NMN / NPN are both used in Class H electrical insulation systems. Nomex® 410 is a single-layer aramid insulation paper, while NMN / NPN combines Nomex® outer layers with a Mylar® polyester film core for a laminated construction.

    Feature Nomex® 410 NMN / NPN
    Material Type Aramid electrical insulation paper Flexible electrical insulation laminate
    Construction Single-layer Nomex® aramid paper Nomex® / Mylar® / Nomex® laminate
    Temperature Class Class H – up to 220°C Class H – 180°C
    Mechanical Strength Good Higher due to laminated construction
    Typical Applications Slot liners, phase insulation, coil wrapping and transformer insulation Slot, phase and interlayer insulation in Class H motors, generators and transformers
    Best Choice When Thin, flexible aramid insulation paper is required A stronger laminated insulation material is required
