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.
