Product Details
Nomex® aramid paper sheets and tubes from DuPont are high-temperature resistant insulation products that exhibit an excellent balance of physical and electrical properties. Made entirely from synthetic aramid polymer, Nomex comes in two forms: short fibers (floc) and microscopic fibrous binder particles (fibrids). It is widely used as electrical insulation for liquid and dry transformers, motors, and generators. Nomex Type 410, a calendered insulation paper, offers 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). It 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 a soft cushioning material when conformability and impregnability are critical. Additional variants include Nomex Type 414, Type 418, Nomex pressboard, T992, T993, and T994.
