    • By using a polymeric film having a dielectric loss tangent of 0.002 or less measured at a frequency in the range of 1 kHz to 1 GHz at a temperature of 25 ° C., heat generation of dielectric loss of capacitors can be reduced and rising of temperature can be inhibited, and, can highly stand the rise of temperature, whereby further miniaturization and increase in capacity of capacitors become possible. Furthermore, the problems in handling that the films are apt to cut or become entangled at the rewinding step can be greatly improved by using polymeric films which are 1 or less in friction coefficient between the films of the same material. Accordingly, the polymeric films are excellent in performance of insulator film, namely, small in dielectric loss tangent, and, moreover, are free from the problems in handling that the films are apt to cut or become entangled at the rewinding step. Furthermore, the polymeric films are suitable for film capacitors.
    • 通过使用在25℃的温度下以1kHz〜1GHz的频率测定的介电损耗角正切为0.002以下的聚合物膜,可以降低电容器的介电损耗的发热和温度的升高 可以被抑制,并且可以高度地承受温度的上升,从而可以进一步小型化和增加电容器的容量。 此外,通过使用相同材料的膜之间的摩擦系数为1以下的聚合物膜,可以大大提高处理在回绕步骤中易于切割或变得缠结的问题。 因此,聚合物膜的绝缘膜的性能优异,即介电损耗角正切较小,而且在回卷工序中,薄膜易于切割或缠绕的问题也不存在。 此外,聚合物膜适用于薄膜电容器。
