Description
Product Overview
NMN Insulation Paper (Polyester Film Aromatic Polyamide Paper Flexible Composite Material) is a high-performance three-layer flexible composite material that combines the superior thermal resistance of DuPont Nomex aramid paper with the exceptional mechanical strength and durability of polyester film. Through an advanced heating and pressing lamination process, this material creates a smooth, stiff insulation solution with excellent dielectric properties.
Engineered for Class F (155°C) and Class H (180°C) temperature ratings, NMN Insulation Paper delivers outstanding tensile strength, edge tear resistance, and electrical insulation performance. Its flexible structure and excellent compatibility with commonly used insulating varnishes make it the ideal choice for motors, transformers, and electrical machinery operating under demanding conditions.
