Product Details
Nomex® aramid paper sheets and tubes are high-temperature resistant insulation products developed by DuPont, known for their excellent balance of physical and electrical properties. Manufactured from synthetic aramid polymer in the forms of short fibers (floc) and microscopic fibrous binder particles (fibrids), Nomex is extensively utilized as electrical insulation in various applications, including liquid and dry transformers, motors, and generators. Nomex type 410, a calendered insulation paper, provides high inherent dielectric strength, mechanical toughness, flexibility, and resilience, and is available in 11 thicknesses ranging from 2 to 30 mils (0.05 to 0.76 mm). This type maintains a dielectric strength of 300 V/mil (12 kV/mm) for several hours at temperatures up to 400°C (750°F). Nomex type 411, which is uncalendered, is offered in thicknesses from 0.13 mm to 0.58 mm and is often used as soft cushioning material or where conformability and impregnability are essential. Additional variants include Nomex® type 414, type 418, Nomex® pressboard, T992, T993, and T994.
