Nomex® 411 Features High Bulk and Conformability
DuPont™ Nomex® 411 is a lower density version of Nomex® 410 that offers increased impregnability and saturability.
DuPont™ Nomex® 411 is a lower density version of Nomex® 410, the original form of Nomex® paper. Due to its lower density, Nomex® 411 has correspondingly lower electrical and mechanical properties than Nomex® 410. However, the tensile strength of Nomex® 411 can be significantly increased through heat treatment under certain specific conditions.
Due to its more open structure, Nomex® 411 offers increased saturability of varnishes and resins compared to Nomex® Type 410. The exact amount of improvement depends on the specific varnish, application technique and product thickness. In one test, with hand-dipped varnish, Nomex® 411 showed a 40% saturability improvement compared to Nomex® 410. With vacuum-pressure impregnation, the saturability improvement was as high as 200%.
This increased impregnability and saturability make Nomex® 411 suitable for use in cast resin applications as turn and layer insulation. Nomex® 411 is also used in applications such as motor phase insulation and transformer coil end filler, where high bulk and conformability are of prime importance.
