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&#xb0; 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.

Biaxially stretched polymer film comprising a decarboxylation catalyst, its use in electrical insulation applications, and process for its production

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.

Process for producing biaxially oriented PET films and use of the same for SMD-technology film capacitors

The present invention relates to a single or multilayer biaxially oriented film having a thickness of &lE;12 &mgr;m, in which T,(TD) is &gE;160&deg; C., S 200 (TD) is &lE;5%, S 200 (MD) is 2-5%, the shrinkage force ratio N,220/N,160 is &gE;4.5; the film fixing peak is &gE;210&deg; C.; the film density is 1.39-1.41 g/cm,, and T,(TD) is the temperature at which the transverse shrinkage begins, S 200 (TD) is the shrinkage in the transverse direction (in %) at 200&deg; C., S 200 (MD) is the shrinkage in the machine direction (in %) at 200&deg; C., N,220 is the shrinkage force (in N) at 220&deg; C. and N,160 is the shrinkage force (in N) at 160&deg; C. in the transverse direction. The invention also relates to a method for forming the film.

Biaxially oriented pet film having enhanced mechanical and shrinking

The invention relates to a biaxially oriented polyester film having a roughness, on at least one film surface, of R.sub.z greater than 1.0 .mu.m (Ra is greater than 0.1 .mu.m), a dielectric strength (AC) greater than 220 kV/mm (the DC dielectric strength is greater than 500 kV/mm) and a migrating fraction in the film of less than 18 .mu.S/cm based on a mass of added particles in a polyester volume of 100 cm.sup.3. The film is particularly suitable for oil-impregnated capacitors.
