Quentys™ resin for thermoplastic solar encapsulant

Developed for producing thermoplastic encapsulant films with no cross-linking and lower temperature lamination.

Encapsulants protect solar panel cells from environmental factors. Traditionally, ethylene-vinyl acetate (EVA) are used, but they have limitations in their resistance to UV radiation and moisture ingress. Polyolefin-based encapsulants offer a superior alternative as they are highly resistant to UV radiation and moisture, withstand extreme temperatures and have excellent electrical insulation properties. Polyolefin materials also offer various recycling options, which can make them an eco-friendly choice for end-of-life management.

Quentys™ resin is developed for producing thermoplastic encapsulant films. Adhesion functionality is directly incorporated in the polymer chain by Borealis’ proprietary copolymerisation technology, also ensuring excellent homogeneity of the film.

Thanks to the polymer’s high melt temperature and high viscosity, there is no need for the encapsulant to be cross-linked. This significantly simplifies both the film making step and module lamination process. Lower temperature lamination is possible, making the solution compatible with next generation Perovskite cell technologies.

Furthermore, non-cross linking feature enables easier separation of the PV module during the recycling step and paves the way for an increased recovery rate of module components.
