Product Description

NMN insulation paper

NMN Insulation Paper is a high-performance electrical insulation material composed of Nomex paper laminated with polyester film (PET) in a Nomex-PET-Nomex structure.

It combines the thermal resistance of aramid paper with the mechanical strength of polyester film, making it an ideal Class H insulation solution for motors, transformers, and other electrical equipment operating under high temperature and electrical stress.

NMN insulation paper is widely used for slot insulation, phase insulation, and inter-layer insulation, ensuring long-term reliability and safety of electrical systems.
