NOMEX 410
NOMEX 410 paper is a rolled insulating paper with high inherent dielectric strength, mechanical toughness, flexibility and resilience.
MOMEX 410 paper is the earliest product of NOMEX paper and is widely used in most electrical equipment.
Available in 12 thicknesses (0.05-0.76mm)(2-30mi), it is used in almost all cases where sheet electrical insulation is known to be required.

NOMEX 410 Features
- Exceptional thermal stability—Temperatures up to 200°C have little or no effect on the electrical and mechanical properties of Nomex®, and useful values are retained at considerably higher temperatures. Moreover, these useful properties are maintained for at least 10 years of continuous exposure at 220°C.
- Outstanding mechanical toughness—Densified Nomex® products are strong resilient and resistant to tearing and abrasion. Thinner grades are also flexible.
- Inherent dielectric strength—In densified form, Nomex® withstands short-term electrical stresses of 18 kV/mm (457 mils) to 40 kV/mm (1,015 mils), depending on product type and thickness, with no need for further treatment with varnishes or resins.
- Broad chemical compatibility—Nomex® is essentially unaffected by most solvents and is unusually resistant to attacks by acids and alkalis. It is compatible with all classes of varnishes and adhesives, transformer fluids, lubricating oils, and refrigerants.
- Excellent flame-resistance—Nomex® products do not melt and, with a limiting oxygen index (LOI) at 220°C above 20.8 (the critical value for combustion in normal air), they do not support combustion.
