AMA Aramid / PET / Aramid
Domestic aramid paper / PET film / aramid paper, Class F - a cost-effective alternative to NMN
AMA is the same three-layer construction as NMN, but uses domestic aramid paper instead of Nomex®. Designed as a cost-effective Class F replacement for NMN in motor slot, liner and turn insulation.
- Temperature class
- Class F (155°C)
- Thickness

Key features
- Domestic aramid paper replaces Nomex® to reduce cost in Class F applications.
- Three-layer construction balances heat resistance, dielectric strength and mechanical strength.
- Multiple thickness/grammage grades for different motor slot insulation needs.
Applications
Class F motor slot insulation, liners and turn insulation; appliance insulation.
Why it fits
If NMN is over-specified for your Class F motor, AMA delivers the same look and feel at a lower material cost.
