Nomex® T410 Polyaramid Disk (Polymetaphenylene isophthalamide)

Nomex® T410 Polyaramid Disk (Polymetaphenylene isophthalamide) brings that calendared aramid paper into a precise circular format for washers, spacers, and masks that must insulate, carry clamp load, and present a clean surface to adjacent parts. The densified structure resists edge fray and holds fastener torque, so disks keep shape in stacks around cores, bobbins, and buswork. Manufacturers use T410 disks as phase separators, pressure-spreading shims, and dielectric masks during impregnation or assembly, taking advantage of the paper’s resilience to survive handling and maintenance without shedding. The smooth face bonds well if laminated, and the material remains stable over a wide service window, helping designs control corona and avoid brittle failure. In high-reliability equipment—motors, transformers, test fixtures, and power modules—the disk format simplifies repeatable positioning and supports consistent clearances. It’s a practical route to robust, electrically quiet spacers that remain tidy and dimensionally true under heat and vibration.
