Products Description

Composition:
NHN 6650 consists of polyimidfilm, being covered with calandered Nomex 1 paper on both sides.

Application:
NHN is used as interlayer insulation in transformers and other electrical machines and appliances.

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, max. width is 920mm, length can be cut as per customer’s requirement
In Roll: 10~920mm width
