Product Details
Nomex® aramid paper sheets and tubes, developed by DuPont, represent a high-temperature resistant insulation solution characterized by a superior balance of physical and electrical properties. Constructed entirely from synthetic aramid polymer, Nomex is available in two forms: short fibers (floc) and microscopic fibrous binder particles (fibrids). This material is extensively utilized as electrical insulation in liquid and dry transformers, motors, and generators. Nomex Type 410 is a calendered insulation paper that delivers high inherent dielectric strength, mechanical toughness, flexibility, and resilience, making it the original form of Nomex paper and widely applicable in various electrical equipment applications. Offered in 11 thicknesses ranging from 2 to 30 mils (0.05 to 0.76 mm), Type 410 can maintain a dielectric strength of 300 V/mil (12 kV/mm) for several hours at temperatures up to 400°C (750°F). Additionally, Nomex Type 411 is available in uncalendered form with thicknesses from 0.13 mm to 0.58 mm and is often chosen for applications requiring soft cushioning or enhanced conformability and impregnability. Other variants include Nomex® Type 414, Type 418, Nomex® pressboard, T992, T993, and T994.
