PTCU Copper Foil Coating PI film
Specification
The PTCU copper foil coating PI film produced by our company is coated with polyimide on one or both sides of the copper foil, without any adhesive, it can work for a long time at more than 200℃. The PTCU PI film has excellent performance for electronic shielding. We can handle different shielded thermal conductive insulation materials according to the needs of customers. The thickness of copper foil can be 3um to 200um, and the thickness of the PI coating can be 5um to 25um. We can process various other metal foil or sheet, which can be customized according to customers' requirements.
Features:
High temperature resistance, high insulation, flame retardant, impact resistance, bending resistance, solvent resistance, radiation resistance.
