      AM/AMA Aramid paper+Polyester Film+Aramid paper

Properties and Application:

AM/AMA is made of one or two layers of aramid paper  with one layer of electrical grade polyester film, which has  good

dielectric properties, high heat resistance and mechanical strength, and suitable for electric motors as slot, phase, turn-

to-turn, liner insulation in F-class Motor.  The AMA is the good lower cost insulation solution way to replace NMN6640.
