Type 410 is a calendered insulation
paper which offers high inherent dielectric strength, mechanical
toughness, flexibility and resilience.
410 is the original form of NOMEXâ
paper, and is widely used in a majority of electrical equipment
applications. Available in 11 thicknesses (2 to 30 mils, or.
05 to .76mm), Type 410 is used in almost every known electrical
sheet insulation application.
densified form, NOMEXâ
aramid products withstand short term electrical
stresses of 450 to 1000 V/mil (18 to 40 kV/mm) depending on
product type and thickness, with no need for further treatment
with varnishes or resins.
products are strong, resilient and (in the thinner grades)
flexible, with good resistance to tearing and abrasion.
up to 200°C (390°F)
have little or no effect on the electrical and mechanical
properties of NOMEXâ
products, and useful values are retained at considerably
these useful properties are maintained for at least 10 years
of continuous exposure at 220°C
essentially unaffected by most solvents, and is unusually
resistant to attack by acids and alkalies. It is compatible
with all classes of varnishes and adhesives, transformer fluids,
Iubricating oil, and refrigerant. Since NOMEXâ
are not digestible, they are not attacked by insects, fungi
equilibrium at 95 percent relative humidity, densified NOMEXâ
papers and pressboards maintain 90 percent of their bonedry
dielectric strength while many mechanical properties are actually
products will not produce any known toxic reactions in
humans or animals, or melt or support combustion in air. NOMEXâ
products are available which meet UL94V-O requirements. Material
