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 which contain 0.25-20% by weight (based on the weight of the film) of a hydrolysis stabilizer based on epoxidized fatty acid esters and/or epoxidized fatty acid glycerides, and a chain extender. 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 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.

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:
Biaxially stretched film with polymeric constituents formed mainly of polyester in which the film includes at least one copper salt and one halide, with the resulting film having an AC (alternating current) dielectric strength of at least 100 kV/mm at 23° C. and 50 Hz. The invention further relates to the use of the film of the invention, in particular in solar modules, and also to a process for its production.

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.
