Flexible Insulation Laminates

NMN / NPN Flexible Laminate Insulation
Nomex / Mylar / Nomex – Class H Rated to 180°C

NMN (also referred to as NPN) is a high-performance, three-layer flexible insulation made from outer layers of Nomex® paper and an inner layer of Mylar® polyester film. This Class H material is designed for electrical systems requiring excellent thermal endurance and mechanical stability.

Key Features:

• Triple-layer laminate: Nomex / Mylar / Nomex construction ensures superior insulation and tear resistance
• Class H thermal rating: Withstands continuous use at temperatures up to 180°C
• Reliable dielectric strength: Suitable for high-voltage and heat-intensive environments
• Flexible & easy to process: Ideal for wrapping, slotting, and cutting during installations

Applications:

• Slot, phase, and interlayer insulation in motor rewinding and transformer repair
• Ideal for dry-type transformers, generators, and Class H-rated electrical equipment

Available Options:

• Available in rolls or by the square metre
• Thickness configurations: 2/2/2 to 5/10/5 microns (Nomex / Mylar / Nomex)
• Custom slit widths available for precise applications

Part of our flexible laminate range, NMN insulation is a trusted solution for high-temperature environments where long-term reliability is critical. Combine with our high-temp sleeving or electrical varnishes for a complete insulation system.
