Abstract

PURPOSE: To obrain a composite film having improved heat resistance, mechanical properties, dielectric strength and properties dimensional stability, and a low hygroscopicity, by laminating and aromatic polysulfone film on one or both sides of an aromatic polyamide film.
CONSTITUTION: An aromatic polysulfone film is laminated on one or both sides of an aromatic polyamide film consisting of 75 mole% or more of m-phenylene isophthaeamide in the repeating structural units without using adhesives. An amine or acid component may be used as the copolymerization component in an amount up to 25 mol%, and p-pherylenediamine, benzidine, etc. may be cited as the amine component; terephthaloyl chlonide, 1,4-naphthalenedicarboxylic acid dichloride, etc., as the acid component.
EFFECT: Films having heat resistance of class F or H as electrical insulating materals, and particularly improved characteristics as heat-resistant electrical insulating materials can be obtained
