Kapton® B

DuPont™ Kapton® B polyimide film is a black, homogeneous opaque film, that exhibits an excellent balance of physical, chemical, and electrical properties over a wide temperature range, with superior dimensional stability at elevated temperatures. The homogeneous pigmentation provides better color integrity against flexural cracking or abrasion in comparison to black coatings or dyes.
