Highly weatherable BOPET solar back sheet containing novel hydrolytic stabilizer


In conventional back sheets for PV modules, BOPET films serve as an electrical insulation layer for decades. In order to protect the electrical insulation BOPET layer from UV and hydrolytical degradation an additional outer protection layer is necessary.

In cooperation with Clariant Plastics & Coatings, BU Masterbatches, Brückner has developed its proprietary solution for an UV and hydrolytically stabilized BOPET film (patent pending).
