Brief Introduction of the Nomex insulation paper:

The Nomex insulation paper is a three-ply laminate with polyester film between two layers of Nomex® paper.
About the Nomex paper:
Ideally suited for a variety of temperature ranges and applications, laminate insulation products based on Nomex® paper help enhance the performance and reliability of rotating machines.
About the polyester film: It has excellent mechanical properties, dielectric strength, and dimensional stability, as well as low water absorption, and good resistance to most chemicals. These general purpose films are often used for industrial laminates and electric motor and cable insulation.
The nomex insulation paper laminates made with Nomex® papers are used in UL systems typically up to 180°C. These laminates are broadly used in the production and repair of motors, generators of many sizes and temperature classes. The most important applications for these laminates are slot liners, wedges and phase insulation in Class H motors and generators, as well as in large and specialty Class F motors.

Main characters of this Nomex insulation paper:

1. Temperature F/H class
2. Excellent heat resistance, dielectric properties and mechanical strength.
3 Good cutting resistance, overload resistance, high rigidity, good compatibility with insulating paint
4. The slots, turns and linings of F-class motors and appliances are insulated.
5. Form: roll, sheet, strip
