Description:
Model Number: NMN 6640Temperature Class: Class F
Thickness: 0.15mm-0.35mm
Width: Normal or Cutting
introduction:
6640 (NMN) is a middle layer of polyster film and formed on bothsides of the Nomex1 paper, heat-resistant grade of F class (155°c)of soft composite material with good mechanical properties, such astensile strength and edge anti-electrical properties and good tearstrength its smooth surface, when the production uses low voltageelectrical zidong offline slot covers and the white insulation, inaddition to also be used as a transformer or other electricalinsulation between the layers
Application:
NMN Flexible Laminates is mainly used as a slotliner, slot closure, phase and turn-to-turn insulation in low ormedium voltage electrical motors. Besides it is also used asinterlayer insulation in transformers and other electricalappliances.
