Biaxially stretched polypropylene film for capacitors |
| abstract |
The present invention relates to a biaxially stretched polypropylene film for a capacitor containing an isotactic polypropylene, wherein the weight average molecular weight (Mw) of the isotactic polypropylene, as measured by gel permeation chromatography (GPC) is 250,000 to 450,000, the molecular weight distribution Mw / Mn is 7 to 12, Mz / Mn is 20 to 40 and the value of a difference obtained by subtracting a differential distribution value when the logarithmic molecular weight Log (M) = 6 from a differential distribution value when the logarithmic molecular weight on a molecular weight distribution curve Log (M) = 4.5 is 8% to 20% with respect to the differential distribution value when Log (M) = 4.5. According to the present invention, an ultra-thin biaxially stretched polypropylene film can be provided for a capacitor having better heat resistance performance and withstand voltage performance. |
