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.

Nomex Paper Flexible Composite Material:Nomex paper is also a good electrical insulator. In the electronics industry, it can be used to isolate electrical conductors and prevent electrical leakage. This helps in improving the efficiency and safety of electronic devices.
However, like any material, Nomex paper also has some limitations. It may be relatively more expensive compared to some other materials, which can be a factor in cost - sensitive applications. Also, its production process may require certain specialized equipment and techniques, which can add to the overall cost and complexity.
Nevertheless, the overall benefits of Nomex paper as a flexible composite material far outweigh its drawbacks. With ongoing research and development, it is expected that its properties can be further optimized, and its applications will continue to expand in new and exciting ways in the future.

6641 F-CLASS DMD Insulating composite paper
As a Class F insulating material (long-term operating temperature of 155°C), 6641 DMD excels in high-temperature environments. Its core layer uses a high-melting-point polyester film (e.g., 6020 electrical insulation polyester film), combined with Class F adhesive, which remains intact (no delamination or blistering) for 10 minutes at 180±2°C. This heat resistance makes it suitable for high-load motors, dry-type transformers, and other equipment, maintaining stable performance even during short-term overloads (e.g., 200°C).
