BN Opaque Black Polyimide Film

 

Description:

BN Black Polyimide Film (e.g. Kapton® B, LIREN® BN film) is an opaque polyimide film. It has high opacity, excellent physical & mechanical properties, good heat resistance and dimensional stability at elevated high and low tempera­tures. The matte black color of BNfilm provides a uniform and aesthetically pleasing appearance while maintaining key physical properties. The uniform pigmentation provides better colour integrity against flexural cracking or abrasion in comparison to black coatings or dyes.

Characteristics

 • Black matt appearance

 • High opacity

 • Good dimensional stability

 • Chemical resistance

 • Flame resistance UL V-0

 • High and low temperature resistance

Application:

BN Opaque Black Polyimide Film can be used in a wide range of industries where opacity, low reflectivity, or aesthetics are required.

 LED circuitry
