Corona Resistance Polyimide Film

In addition to the very good performance of high and low temperature resistance, electricity insulativity, radiation and etching resistance, it also processes very excellent performance of corona resistance and thermal conductivity, TY6251-FCR (single side, double sides), painted F46 glue on the surface of the single side or double sides of the corona resistance polyimide film. Slit with different width after drying and rolling. The product processes both the good property of corona resistance polyimide film and melt and shape at 360℃-380℃ at half minute.
