Kapton® B

 
 
 

Kapton® B black, homogeneous opaque polyimide film

DuPont™ Kapton® B polyimide film exhibits an excellent balance of physical, chemical, and electrical properties over a wide temperature range, with superior dimensional stability at elevated temperatures.

The matte black color of Kapton® B provides a uniform, aesthetically pleasing appearance while maintaining key physical properties. The homogeneous pigmentation provides better color integrity against flexural cracking or abrasion in comparison to black coatings or dyes. These characteristics make it ideal for use in many industrial applications where opacity, low reflectivity, or aesthetics are required.

Applications include:

  • Heaters
  • Antenna
  • LED circuitry
  • Applications requiring precision laser ablation
