HYDROLYSIS-RESISTANT BIAXIALLY STRETCHED FILM, ITS MANUFACTURING METHOD AND CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide a hydrolysis-resistant biaxially stretched film having a high tracking-resistance voltage, producible at a low cost and suitable as a film for a capacitor exhibiting stable electric characteristics by using a hydrolysis-resistant agent having gas-generation preventing properties.

SOLUTION: The hydrolysis-resistant biaxially stretched film comprises a thermoplastic resin as the main component, contains at least one hydrolysis- resistant agent having gas-generation preventing properties and has a thickness of 0.5-12.0μm, where the alternating current withstand voltage is at least 190 kV/mm and a film surface roughness is at most 150 nm.
