Product Details
Nomex® aramid paper sheets and tubes, manufactured by DuPont, are high-temperature resistant insulation products that exhibit an exceptional balance of physical and electrical properties. Made entirely from synthetic aramid polymer, Nomex is available in two forms: short fibers (floc) and microscopic fibrous binder particles (fibrids). Widely adopted for electrical insulation in liquid and dry transformers, motors, and generators, Nomex type 410 is a calendered insulation paper providing high inherent dielectric strength, mechanical toughness, flexibility, and resilience. This original form of Nomex paper is available in 11 thicknesses ranging from 2 to 30 mils (0.05 to 0.76 mm) and is utilized in a majority of electrical equipment applications. It is capable of maintaining a dielectric strength of 300 V/mil (12 kV/mm) for several hours at 400°C (750°F). Nomex type 411, which is uncalendered, comes in thicknesses from 0.13 mm to 0.58 mm and is often used for soft cushioning applications where conformability and impregnability are vital. Other available types include Nomex® type 414, type 418, Nomex® pressboard, T992, T993, and T994.
