Description:
BYHS high-matted printable polyimide black film is based on BY black polyimide film or CN polyimide film, which is extruded and formed in one time, presenting a high matte black on one side and a regular PI on the other. Can be printed as a high temperature label.
Features:
500℃ Hating resistant on short time, one side produces viscosity, environment-friendly with halogen free, highest UL-94 flammability rating:V-0.
