DuPont Nomex 400 series of insulating paper

Nomex 410 is the raw material of Nomex insulation paper, because it has the characteristics of the ideal balance, and in a wide range of applications to demonstrate a mature and stable performance. As the world's highly acclaimed Over the past 50 years, Nomex has met the growing demand of the electrical industry and is the preferred insulation material for most electrical equipment applications.

Nomex 400 series, the most famous is the Nomex 410 insulating paper, has now become the performance, reliability and service life of the classic benchmark products, this benchmark is all other insulating materials compared to the benchmark.


The outstanding features of Nomex 410, as well as other products of the Nomex 400 series, come from the ideal balance of the five key features:

Excellent thermal stability - temperatures up to 200 DEG C have little or no effect on the electrical and mechanical characteristics of Nomex, and can be maintained even at very high temperatures. In addition, even if exposed to a 220 DEG C environment for at least a continuous working for 10 years, these excellent characteristics can still be maintained.

Superior mechanical toughness - enhanced Nomex product is robust and has the ability to recover, as well as resistance to tear and wear. Thinner grades can also provide flexibility.

The dielectric strength in strengthening products, according to the type and thickness of the products, without coating or resin treatment, Nomex had a short period of time can withstand 18 kV/mm (457 mil) to 40 kV/mm (1015 mil) of the electric stress.

Broad chemical compatibility - Nomex is largely free from the effects of most solvents and has an unusual tolerance to acid and alkali corrosion. It is compatible with all types of paints and adhesives, transformer oils, lubricants and refrigerants.

Excellent flame retardancy - Nomex products will not melt, at 220 degrees C limit oxygen index (LOI) more than 20.8 (usually the critical value of combustion in the air) will not burn.


Nomex 410

Nomex 410 is used in almost all sheet insulation applications. This high density product has inherent high dielectric strength, mechanical toughness, flexibility and resilience. The product thickness range from 0.05 mm (2 mil) to 0.76 mm (30 mil), the proportion of the range from 0.7 to 1.2.

Typical applications of Nomex 400 series
