AMA composite material is a three-ply flexible laminate consisting of polyester film laminated on both sides with Aramid fiber paper, shows high thermal resistance, excellent mechanical properties, and electrical properties, it is designed for automatic insertion machine. APA (Laminated Aramid) serves as an advantageous replacement for NPN (Laminated Nomex) due to its superior mechanical and thermal properties and competitive pricing with exceptional strength, heat resistance, and durability, APA outperforms in challenging environments, providing enhanced reliability and longevity compared to NPN.

AMA is mainly used as a slot liner, slot closure, phase-to-phase and turn-to-turn insulation in low or medium voltage electrical motors of class 'F' (155 °C) or class 'H' (180 °C) insulation system, in addition, it's also used as interlayer insulation in transformers and other electrical machines and appliances.
