Dupont's™ Kapton® Type HN is a tough, aromatic polyimide film, exhibiting an excellent balance of physical, chemical, and electrical properties over a wide temperature range, particularly at unusually high temperatures.

With a working temperature between -269 ºC and 400 ºC, and because its thermal properties, Kapton® is used for the creation of flexible printed circuits and, due to it good adhesion to ABS plastic, as contact surface in 3D printers heated beds, and as adhesive tape for extruders and hot ends.
