Transparent, biaxially oriented polyester film with a high portion of cyclohexanedimethanol and a primary and secondary dicarboxylic acid portion and a method for its production and its use |
摘要 |
The invention relates to a biaxially oriented film, predominantly formed from a polyester whose diol component includes at least 80 mol-% of 1,4-cyclohexanedimethanol (CHDM), and whose dicarboxylic acid component includes 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 18 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. |
