BL type is black polyimide film,one side glossy,the other matte, specially for label application.

CEN ®BL Polyimide Film

CEN®BL polyimide film is a printable film that has the same thermal and chemical properties as CEN®CN Polyimide Film, which offers excellent performance in temperatures from -269-400°C. CEN®BL is pigmented to provide contrast and eliminate the need for opaque coatings. Printing on BL can be accomplished with thermal transfer and laser printing.

 

Applications: Labels for high temperature, cryogenic storage, harsh chemical environments, and printed circuit board identification.
