摘要:
The invention relates to a biaxially oriented film, predominantly formed from a polyester whose diol component includes at least 35 mol-% of 1,4-cyclohexanedimethanol (CHDM) and additionally contains at least one further diol different from CHDM. The dicarboxylic acid component of the polyester 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 of the polyester includes a main dicarboxylic acid component forming an at least 55 mol-% portion of the dicarboxylic acid component, chosen from 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-% of the dicarboxylic acid component, 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.
摘要:
The invention relates to a hydrolysis-stable polyester film comprising a polyester, whose thickness is preferably in the range from 0.4 to 500 μm. The film comprises polyester and at least one hydrolysis stabilizer and is distinguished by its low hydrolysis rate. The invention furthermore relates to a process for the production of the film and its use.
摘要:
The invention relates to a multilayer polyester film comprising a hydrolysis stabilizer, wherein the hydrolysis stabilizer is an epoxidized alkyl ester of fatty acid or is a mixture of epoxidized alkyl esters of fatty acid or is an epoxidized fatty acid glyceride or is a mixture of epoxidized fatty acid glycerides, and at least one external layer of the film does not comprise the hydrolysis stabilizer. The form in which the hydrolysis stabilizer is added to the polyester can be that of dry liquid, absorbed by a carrier material.
