Product Details

NOMEX insulating paper is an aromatic polyamide, collectively referred to as aromatic polyamide. Made from two types of aromatic polyamide polymers. The fine fibrous bonding particles chromatographic fibers are cut directly from the polymer under high shear. These particles are mixed with short fibers of a certain length cut from the filaments. It has a unique and appropriate balance of performance, and has been widely used in transformers, motors, generators and other electrical equipment for many years to improve the reliability of electrical insulation.


It is a calendered insulating paper with high inherent dielectric strength, mechanical toughness, flexibility and resilience. Nomex T410 has excellent flame retardant properties.

Scope of application: T410 can be widely used in most electrical equipment. It has 12 thicknesses (0.05-0.76) (2-30mil) and is used for almost all known electrical sheets


1. Inherent dielectric strength

The calendered product can withstand the short-term voltage field strength of 18-40KV/mm, without further treatment with varnish and resin; because the product has a low dielectric constant, the electric field distribution between the insulating and cooling medium is more Evenly

2. Mechanical toughness

Elasticity, tear resistance and abrasion resistance are good, thinner products are flexible;

3. Thermal stability

The product has the approval of 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;

4. Chemical compatibility

Basically not affected by most solvents, and very resistant to acid and alkali corrosion. It is easily compatible with all varnishes, adhesives, transformer fluids, lubricating oils and cooling agents.

5. Low temperature performance

At the boiling point of nitrogen (77K), the tensile strength exceeds the strength value at room temperature;

6. Not sensitive to moisture

When the product is 95% wet, its dielectric strength is 90% of that in a completely dry state. At the same time, many mechanical properties are actually improved;

7. Radiation resistance

Even if the intensity of ionizing radiation reaches 800 Mrad, the product is basically unaffected, and it still maintains its mechanical and electrical properties after 8 times of this dose of radiation;

8. Non-toxic/flammable

The product will not cause any known toxic reactions to humans or animals. The product does not melt in the air and does not support combustion. And at 220 °C, its limited oxygen index (LOI) is greater than 20.8 (the critical value of general empty combustion), so It will not burn. The product meets the flame resistance requirements of UL94V-0.
