Remark: Highlighting our standard as a premier electrical insulation film manufacturer, the values above are typical TDS values and are not guaranteed values. MD refers to machine direction and TD refers to transverse direction. Electrical strength for 100μm and below is tested in air; above 100μm is tested in oil. Dissipation factor, relative permittivity, and volume resistivity are type inspection items; other items are delivery inspection items.
