BL polyimide film is a black, homogenous opaque film, one side matt while another glossy. 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.
