摘要:
The invention relates to an aqueous coating composition which comprises a mixture of polyvinylpyrrolidone, a surfactant and optionally an adhesion-promoting polymer. This mixture is suitable for inline coating of biaxially oriented polyester films. The thus obtained films feature a characteristic hydrophilic surface which prevents the fogging of the films with water droplets.

摘要:
This invention relates to a three-layer, polyester film with A-B-C structure, which includes a base layer B, preferably formed from PET, disposed between cover layers A and C. The cover layers contain polyester with ethylene terephthalate and/or ethylene isophthalate units and, as an additional polymer poly(m-xylene-adipamide) in an amount of 10 to 45 wt. %. At least one of the cover layers also contains an antiblocking agent preferably with a mean particle diameter of 2 to 5 μm. This film has a high oxygen barrier.
摘要:
The invention relates to a transparent, biaxially oriented polyester film with a base layer B formed from at least 80% by weight of a thermoplastic polyester, and with at least one outer layer A. The outer layer A includes polyesters and poly(m-xyleneadipamide) in certain concentrations. The invention further relates to the use of the film and to a process for its production. The transparent film has very low atmospheric-oxygen transmission and exhibits very good adhesion between the respective layers. It is particularly suitable for packaging purposes, specifically for the packaging of foods and of other consumable items.
摘要:
The invention relates to a transparent, electrically conductive, biaxially oriented, single- or multilayer polyester film which includes a coating composed of (a) conductive (ITO) indium tin oxide particles or (ATO) antimony tin oxide particles, or of a mixture of these. The film further include other conductive components (b). The other conductive components (b) may be present either in the coating including ITO particles and/or ATO particles or in a layer in contact therewith. The conductive component (b) may also be a metal layer in contact with the ITO and/or ATO. The film is only oriented or relaxed prior to application of the ITO and/or ATO coating. The invention further relates to a process for the production of the film, and its use.
摘要:
The invention relates to biaxially oriented polyester films which contain 0.1-5.0% by weight (based on the weight of the film) of a hydrolysis stabilizer based on epoxidized fatty acid esters and 0.2-10% by weight (based on the weight of the film) of epoxidized fatty acid glycerides, the epoxidized fatty acid esters having a mean molecular weight of at least 425 g/mol. Such films find use in outdoor applications, as a ribbon cable, as a backside laminate of solar modules and in electrical insulation applications.

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.
摘要:
The invention relates to biaxially oriented polyester films that include a chain extender in addition to the polyester. Such films find use in all applications typical of biaxially oriented polyester films, especially in outdoor films, as a ribbon cable, as a backside laminate of solar modules and in electrical insulation applications.
