6640-Polyester Film/ Nomex Paper Flexible Composite Material

Product features
1. Excellent insulating properties:
6640NMN composite insulating paper is made of multi-layer materials composite, especially its outer layer of DuPont Nomex polyaromatic fiber paper, which provides the material with excellent insulating properties. This insulating property can also remain stable in high temperature environment to ensure the safe operation of electrical equipment.
2. High temperature resistance:
The material has excellent high-temperature resistance, usually able to work continuously in a high-temperature environment of 200 ℃, and can withstand short periods of time at higher temperatures. This characteristic makes 6640NMN composite insulating paper especially suitable for electrical equipment in high temperature working environment.
3. Abrasion resistance:
Its inner and outer two layers of polyimide film has very good wear resistance, which can effectively avoid the motor and other electrical equipment due to wear and tear failure or reduce performance.
4. High mechanical strength:
The fiber paper layer enhances the mechanical strength of the material so that it can withstand greater mechanical stress and impact.
5. Good flexibility and dielectric properties:
The material has good flexibility and is easy to process and install; at the same time, its excellent dielectric properties ensure the stable operation of electrical equipment in complex electromagnetic environments.
6.Green:
6640NMN composite insulating paper meets the EU RoHS standard detection test 2002/95/EC directive, is lead-free, nickel-free, cadmium-free green electrical products.

Product introduction
6640NMN aramid composite insulating paper is an insulating material made of a multi-layer material composite, usually consisting of an intermediate layer of electrotechnical PET insulating polyester film and two layers of DuPont Nomex polyaromatic fiber paper. The design of this three-layer structure makes the material outstanding in insulation, high temperature resistance, abrasion resistance and mechanical strength.
The material is widely used as slot insulation, liner insulation and turn-to-turn insulation in stator windings of electric motors and appliances. At the same time, it is also suitable for interlayer insulation, end sealing insulation and liner insulation in dry-type transformers. Due to its excellent performance and wide range of applications, 6640NMN aramid composite insulating paper has a very important position in the electrical equipment manufacturing industry.
In addition, 6640NMN aramid composite insulating paper produced by different manufacturers may have slight differences in specifications, thickness, color, etc., but generally maintains its excellent performance characteristics. Therefore, when selecting and using this material, comprehensive consideration needs to be made according to specific application scenarios and needs.
