Kapton® PRN multi-layer heat-fusible composite film

DuPont™ Kapton® 150PRN411 is ideal for insulating copper conductor used in high temperature magnet wire applications.

It is a multi-layer heat-fusible composite film that enables higher operational temperature functionality and improved abrasion resistance. 150PRN411 consists of a layer of 25 micron thick Kapton® HN polyimide film between two layers of high melt temperature fluoropolymer. One of the fluoropolymer layers is approximately ten microns thick and the other layer is approximately three microns thick.
