AHA Laminated – Aramid + Polyimide

AHA Laminated – Aramid + Polyimide | High-Temperature Electrical Insulation Laminate

AHA Laminated (Aramid + Polyimide) is a premium flexible laminated electrical insulation material developed for high-temperature and high-stress applications. It is a three-layer composite laminate consisting of a polyimide film core bonded with aramid paper on both sides using high-temperature adhesive. This structure provides exceptional thermal endurance, excellent dielectric strength, and superior mechanical stability.

AHA Laminated – Aramid + Polyimide | High-Temperature Electrical Insulation Laminate

The polyimide film core delivers outstanding heat resistance, dimensional stability, and electrical insulation, while the aramid paper layers add mechanical strength, tear resistance, and long-term aging stability. Together, these layers ensure reliable insulation performance under extreme thermal and electrical conditions.

AHA laminated insulation is widely used in high-temperature motors, generators, transformers, traction motors, EV systems, and aerospace electrical equipment. It is ideal for slot insulation, phase insulation, interlayer insulation, and insulation barriers where Class H and higher thermal performance is required.

Designed for demanding environments, AHA Laminated – Aramid + Polyimide offers a high-reliability insulation solution for advanced electrical and industrial applications.
