Dupont Nomex 410 and The 400 Series
Delivering superior performance and reliability to insulation of transformer&motor, EV battery and other electronic components.

Dupont Nomex Materials

High Temp Resistant Materials Provide Superior Electrical Insulation

Dupont Nomex paper is a unique aramid enhanced cellulose material, composed of high quality electrical grade cellulose pulp. Differentiated by the density of paper and thickness ranging, the series can be classified as: the most typical model Nomex 410 and some other Nomex 400 series, like Nomex 411, Nomex 414, Nomex 416LAM, and Nomex 464LAM. They all feature superior high temperature resistance, strong dielectrical strength and mechanical properties. And they are also compatible with all classes of varnishes and adhesives, transformer fluids, lubricating oils and refrigerants, which is mainly functioned as insulation in various industries, such as transformers insulation, motors insulation, power switch insulation, power cable insulation, PCB board insulation, lithium battery insulation and other electrical industries insulation.
