6650 NHN INSULATION PAPER 
Detail
Code: 6650 Series: insulation paper
Spec: 0.13-0.45 Material: NOMEX
Color: BROWN Brand: DUPOND

NHN/NKN (Nomex paper/Polymide film/Nomex paper)is a Triple layer electrical insulation material of thermal class  H 180℃, consisting of polymide film covered with Du Pont Nomex paper. The polymide film giving the product mechanical and dielectric features, while the Du Pont Nomex paper gives the thermal resistance.This NHN has excellent electrical.mechanical,and impregnating properties.

Combined flexible materials NHN main paramete:

No.
