Nomex® 411


DuPont™ Nomex® 411

Nomex® 411 is a lower-density version of Nomex® 410. It is available in thicknesses ranging from 0.13 mm (5 mil) to 0.58 mm (23 mil), with a specific gravity of 0.3 and correspondingly lower electrical and mechanical properties. It is used in applications such as motor phase insulation and transformer coil end filler, where high bulk and conformability are of prime importance, along with increased impregnability and saturability.
