Mechanical and dielectric performance improves with varnish impregnationAvailable with internal diameters from 2.0mmWall thicknesses, from 0.350 mmUnique 5 layer DuPont™ Nomex® grade 411 and Kapton® HN construction provides excellent mechanical and dielectric strengthEndcaps of any diameter can be manufactured with a variety of Constructed from UL approved materialsSuitable for Class H applications and temperatures up to 180°C

Multilayered precision-wound protective Endcap made from DuPont™ Kapton® film and Nomex®. Designed for use in varnish impregnated electrical motors, Two layers of DuPont™Nomex® type 411 are bonded to a three-layer protective DuPont™ Kapton® sheath. The uncalendared inner insulator has the property of wicking varnish during the impregnation process, boosting its mechanical and dielelectric properties and helping to secure the Endcap in position. These Endcaps maintain electrical resistivity, dimensional stability and strength at high temperatures and in the most demanding applications. Sonic welded seal is chemically resilient and further contributes to the robustness and reliability of the eventual product.
