    摘要: The invention relates to electrical insulation films incorporating biaxially oriented film predominantly formed from polyester. The polyester has a diol component that includes at least 80 mol-% of 1,4-cyclohexanedimethanol (CHDM) and a dicarboxylic acid component containing at least 80 mol-% of one or more benzenedicarboxylic acid(s) and/or one or more naphthalene dicarboxylic acid(s). The dicarboxylic acid component includes a main dicarboxylic acid component forming an at least 55 mol-% portion, chosen from either 2,6-naphthalene dicarboxylic acid or terephthalic acid. The dicarboxylic acid component further includes a secondary dicarboxylic acid component, present in an amount of at least 5 mol-%, with the secondary dicarboxylic acid component differing from the main dicarboxylic acid component. The invention further relates to a method for producing the film and its use.
