AMA Laminates (Aramid + Polyester Film + Aramid)

AHA Laminates (Aramid Paper + Polyester Film + Aramid Paper) are high-performance flexible electrical insulation materials designed for high-temperature applications. With aramid layers on both sides of a polyester film core, AHA laminates offer excellent dielectric strength, superior thermal stability, and long service life. Widely used in motors, transformers, and generators, AHA laminates are ideal for slot, phase, and interlayer insulation, making them a preferred choice for Class F and Class H insulation systems in demanding electrical environments.

Overview

AMA laminates are flexible insulation materials made by bonding polyester film between layers of aramid paper. These laminates are known for their excellent thermal resistance, high dielectric strength, and strong mechanical properties, making them suitable for Class F insulation systems.

They provide a balanced combination of flexibility and durability, ensuring reliable performance in demanding electrical applications.
