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

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.

 

Characters:

High-temperature resistance, high voltage-resistance and tensile strength resistance

High-temperature resistance, good radiation resistance

Stable chemical property

Good at shielding and matt appearance

Halogen-free, environment-friendly, flame-retardant, catching the highest UL grade level-UL 94V-0

Applications:

Black tape at high temperature

Black matt flame-retardant label at high temperature

Black insulation washer/piece.

Black stiffiner
