Aramid Lamination Paper AMA Paper
Main parameters:
- Insulation class: F class (155 °C)
- Color: white
- Width: 10-980mm
- Thickness:0.12-0.5mm
- Can be customized
The AMA insulation paper has excellent heat-resistant, electrical, and mechanical properties. The performance is totally according with the standard of NMN(GB/T5591.3-2008), and it has the very similar property as AMA.The price is cheaper than NMN insulation paper. It’s perfect substitute of NMN.
Aramid Lamination Paper AMA Description
The Class F AMA flexible laminate insulation paper is a three-layer flexible composite material, produced by using F Class adhesive to adhere the polyester film with hot rolling Aramid paper on both sides.
- Three layers: polyester film is bonded with hot rolling Aramid paper (A).
- Middle Layer: Polyester film(PET) for Electrical Purposes
- Outer Layer: hot rolling Aramid paper (A).
According to different thicknesses of Aramid paper, AMA can be divided into two kinds. The thicker one(0.04mm) with yellow line, the other one(0.05mm) with orange line.
