AMA Insulating Paper

Product Introduction
AMA Insulating Paper is a three-layer flexible composite insulating material (aramid paper / polyester film / aramid paper) with an insulation class of Class F (155°C). It combines the high-temperature resistance of aramid paper with the high dielectric strength of polyester film. Widely used in motor slot insulation, turn-to-turn insulation, transformer layer insulation, and other applications, it offers excellent mechanical and electrical properties. It is a cost-effective alternative to NMN insulating paper.
