RenewSys launches PRESERV 300 TN series transparent non-fluoropolymer backsheet
It is suitable for applications where structural considerations and environmental exposures are primary concerns
A few of the applications are solar billboards and streetlights
Indian PV backsheet and encapsulant maker RenewSys India Pvt. Ltd. has released its PRESERV 300 TN series backsheet for ‘emerging’ solar applications.
Among the polymer-based film’s physical properties, the company emphasizes transparency and low density (g/cm³). Without sharing the baseline data for this comparison, the company states that its ‘lightweight’ backsheet comprises a non-fluoropolymer composition. Of the 2 layers, a Biaxial Oriented Polymer – whose surface is treated by hydrolysis (H-BOP) – is placed on the airside. This layer, with improved surface adhesion, is subsequently integrated with a primer layer on the cell side via a thermal process. It also offers low-carbon solutions compared to fluoropolymer-based backsheets, which often release fluorinated compounds during high processing temperatures. This, in turn, makes the backsheet suitable for recycling at the end of its life.
In terms of durability, it is resistant to external damage, such as scratches. In addition, the company says the product’s thermally integrated production process bonds the 2 layers in an ‘inseparable’ manner, improving resilience to delamination. These characteristics, including its light weight, make it suitable for applications where structural considerations and environmental exposures play a key role. A few of these applications are solar billboards and streetlight systems, RenewSys noted.
However, the company’s official LinkedIn post didn’t share technical details of peel strength, adhesion, elongation limit, and tensile strength, among others.
