Our Endurance backsheets have the strongest core layer on the market – giving your market-leading protection against moisture and other threats.
At DSM we use a super moisture-resistant polymer called polyolefin (PO) for our core backsheet layer that is so strong it doesn’t even need an external protective layer in moderate climates. It’s far superior to the traditional PET filler, which is moisture-sensitive, ages quickly in sunlight and requires heavy, expensive stabilization and protective layers.
Although this particular DSM innovation is new to solar, the thinking behind it is based on more than 50 years of material science expertise. Which means that our Endurance backsheet not only delivers market-leading protection against moisture (transmission rate and hydrolysis); it also provides excellent electrical insulation and protection against mechanical abrasion and UV.
Whichever Endurance backsheet you choose, you can rest assured that it is made with a durable strong polyolefin core. What else would you expect from an established $10b global science brand?
