耐电晕聚酰亚胺薄膜

产品说明
    6051-CR耐电晕聚酰亚胺薄膜除具有普通聚酰亚胺薄膜的耐高、低温性、电绝缘性、耐辐射性、耐腐蚀性等特性外,同时具有超强的耐电晕性能及良好的导热性。
    6051-FCR(单面、双面):在耐电晕聚酰亚胺薄膜单面或双面涂敷F46乳液,经烘干、收卷、分切而成。该薄膜即有耐电晕聚酰亚胺薄膜的特性,同时在360℃-380℃半分钟熔融成型.

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.
