Kapton is a polyimide film, manufactured by DuPont Electronics is an excellent choice for Kapton Flat Washers in applications requiring a tough, chemically resistant material.  Used as Kapton Washers, they also exhibit superior electrical properties. It is a very stable material over wide temperature range from minus 273 to plus 400 degrees centigrade, (-459 to 752 degrees F).

Washers made with this material can be used in aircraft, x-ray and 3D printing applications to name just a few.
