Why specify Nomex® for plastic washers?

Nomex® is DuPont's aramid paper — a flexible, paper-format high-temperature electrical insulator widely specified in transformers, motors, and generators. Cannon Gasket die-cuts custom Nomex washers, spacers, and insulators for high-temperature electrical applications.

Properties of Nomex® plastic washers

Cannon Gasket cuts Nomex® plastic washers to your drawing in durometer and thickness specifications of 0.002" to 0.030" thickness. Excellent resistance to thermal aging, flame, radiation, and most industrial chemicals. Maintains mechanical and dielectric properties at elevated temperatures.

Nomex® tolerances and customization

Standard dimensional tolerances on Nomex® plastic washersland around ±0.010" to ±0.015" on OD and ID, depending on material durometer and thickness. Tighter tolerances are available on select grades. Cannon Gasket cuts Nomex® to custom profiles in-house and matches lead times to your production volume. PSA backing, pad printing, custom packaging, and kitting are all on the menu when you need them.

How Nomex Performs

- Continuous-use temperature to +428°F (220°C). - Excellent dielectric strength. - Inherent flame resistance. - Available in grades 410, 411, 414, and specialty variants. - Flexible — drapes and conforms in slot insulation applications.

Common Washer Applications

Power and distribution transformer winding insulation, electric motor and generator slot insulation, switchgear, aerospace electrical components, and high-voltage electrical assembly insulators.
