NMN Nomex insulation paper introduction

NMN insulation paper is a soft composite material composed of a middle layer of Polyester film and Nomex paper on both sides, with a heat resistance grade of F (155°C).

Material properties:

Nomex layer: high temperature resistance, flame retardant, high mechanical strength.

Polyester film layer: excellent electrical insulation performance and chemical resistance.

Thickness: Common thickness is 0.15mm to 0.5mm.

Heat resistance grade: usually F (155°C).

Electrical insulation performance: excellent, suitable for high frequency and high voltage environment.

Mechanical properties: good flexibility and strong tear resistance.

Flame retardant: Nomex layer provides good flame retardant properties.

NMN insulation paper application areas:

Suitable for insulation of electrical equipment such as motors, transformers, generators, etc.

Commonly used in occasions requiring higher mechanical strength and flexibility.

Suitable for high frequency and high voltage environment.

Summary of the main differences between NMN and NHN

The difference between NMN insulation paper and NHN insulation paper lies in the film used in the middle. NMN insulation paper uses Polyester film, while NHN uses Polyimide film.

Temperature resistance grade: NMN insulation paper is usually F grade (155°C), and NHN insulation paper is H grade (180°C)

Mechanical properties: NMN insulation paper has good flexibility and strong tear resistance. NHN insulation paper has high bonding strength and good anti-delamination performance

Typical applications: NMN insulation paper is used for: motor, transformer, generator insulation. NHN insulation paper is used for H-grade motor and transformer insulation.

Recommendations for choosing NMN and NHN

If higher flexibility and high-frequency performance are required, choose NMN insulation paper.

If higher temperature resistance and bonding strength are required, choose NHN insulation paper.

These two types of insulation paper have their own advantages, and the specific choice should be determined according to the actual application requirements (such as temperature, mechanical stress, electrical performance, etc.).
