Products Description

Composition:
NMN 6640 consists of PET film, being covered with calandered Nomex 1 paper on both sides.

Application:
NMN is used as slot liner, slot closure(wedge) and phase insulation in the production of low voltage motors.

Performance:
NHN insulation paper is a combined flexible material, thermal rating class N(180℃~200℃), with good mechanical property such as high tensile strength, high edge tear resistance, high electrical strength. It has smooth surface which allows a free-trouble manufacturing for low voltage motor.

Storage:
Under normal conditions (20℃,50% relative humidity), can be stored indefinitely

Supply condition:
Cut in sheet, around 1000*914mm
In Roll: 5~914mm width
