NMN Insulation Paper Description
Brief introduction of the NMN Insulation Paper
The NMN 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.
