NMN6640 Nomex Mylar Nomex Composite Insulation Paper

NMN6640 is a three-layer flexible composite insulation laminate, constructed with two outer layers of DuPont Nomex aramid paper and a middle core of PET Mylar polyester film, bonded by high-temperature acid-free adhesive. Rated Class F (155°C) and Class H (180°C, continuous 180°C working temperature), it complies with GB/T 5591.3 and IEC international electrical insulation standards.

As an upgraded alternative to traditional DMD insulation, NMN6640 delivers superior thermal stability, dielectric performance and mechanical toughness, widely adopted in heavy-duty motors, dry-type transformers and new energy traction equipment worldwide.
