The invention relates to biaxially oriented polyester films which contain from 0.1 to 5.0% by weight (based on the weight of the film) of a hydrolysis stabilizer based on epoxidized fatty acid esters and 0.2-10.0% by weight (based on the weight of the film) Weight of the film) contains epoxidized fatty acid glycerides, wherein the epoxidized fatty acid esters have an average molecular weight of at least 425 g / mol. Such films are used in outdoor applications, as ribbon cable, as a backside laminate of solar panels, and in electrical insulation applications. |
