For many years ,6640 Nmn Nomex Insulation Paper has been widely used in motors, generators and other electrical equipment to improve the reliability of electrical insulation. The following are the characteristics of NMN insulation paper
1. Mechanical toughness
The calendered NMN insulation paper has very high strength, good elasticity, tear resistance and abrasion resistance, while the thinner has more flexibility.
2. Thermal stability
6640 Nmn Nomex Insulation Paper has the UL material temperature rating of 220°C, which means that it can maintain effective performance for more than 10 years even if it is continuously placed at 220°C environment.
3. Chemical compatibility
NMN insulation paper is basically unaffected by most solvents with high resistance to acid and alkali corrosion. It is also compatible with all varnishes, adhesives, transformer fluids, lubricants and cooling agents. In addition, NMN insulation paper will not be damaged by insects, fungi or mold.
4. Not sensitive to moisture
When the relative humidity of NMN insulation paper is 95%, its dielectric strength is 90% of that in completely dry state. At the same time, many mechanical properties have actually improved.
5. Radiation resistance
6640 Nmn Nomex Insulation Paper is basically not affected even if the intensity of ionizing radiation reaches 800 megarads. Whats more, even after 8 times of this dose of radiation, it still maintains its mechanical and electrical properties.
Our NMN insulation paper products are reliable in quality, high in credibility with favorable prices. They have been favored by customers for many years.
