Description：
CNA Single-Side Thermocompression bonding polyimide film is made up by CEN® CN coating polyimide adhesion, under certain temperature and pressure, one side will produce viscosity due coating polyimide adhesion. Not only has the characteristics of polyimide film, but also has more excellent performances in bonding strength.
Features：
Single adhesive, high insulation, environment-friendly with halogen free, highest UL-94 flammability rating:V-0.
Structure：
