Borealis is a leader in the global polyolefin industry, backed by a strong and strategic ownership foundation shared with our joint venture Borouge.
We have a strong track record of constant growth that enables us to advance innovative ideas all over the world in various industries, including automotive, piping, healthcare, packaging, and wire and cable.
Our experience partnering with the energy industry includes 45 years of innovating demanding cable applications for which reliability and performance are a must. Today, we continue to drive our international expansion, establishing local presences to keep pace with the growth of the global solar market.
Throughout the value chain we strive for effective cooperation with our business partners to ensure our products meet their expectations. And by actively collaborating with international standardisation bodies, we take responsibility for securing the long-term performance of solar modules and protecting the environment.
Borealis has introduced new polyolefin based encapsulant film grades (Quentys™ BPO) for solar photovoltaic modules. The new encapsulant is thermoplastic in nature and is free of organic peroxide. The lamination cycle time with this encapsulant can be reduced significantly compared to conventional EVA and other polyolefin based encapsulants.
Third-party comparative testing* confirms that Borealis encapsulants extend the lifetime of solar modules and increase their power output over time because they offer industry-leading resistance against:

Borealis and Borouge, leading providers of innovative, value-creating plastics solutions, are supporting a Belgium-based racing team taking part in the 2019 Bridgestone World Solar Challenge in Australia. Known as the world championship for solar cars, the 3,000-km race across the outback is the ultimate test for a solar-powered vehicle.
In the current study, we present the evaluation of solar PV modules made with the Borealis encapsulant after various accelerated ageing tests, like damp heat, thermal cycling, humidity freeze test and PID test.
In the current study, we present the evaluation of solar PV modules made with the Borealis encapsulant after thermal and UV ageing.
In the current study, we present the evaluation of solar PV modules made with Quentys™ BPO and reference EVA encapsulants after a combined stress test sequence developed by Fraunhofer ISE, Freiburg, Germany.
Borealis encapsulants offer improved reliability and processing in the lamination process.
In addition to processing benefits, our products also provide secondary advantages.
The outstanding processability of our encapsulants ensures optimised productivity.
Our materials are suitable for key market segments, enabling distinctive solar module capabilities.
Polypropylene (PP) based advanced compounds designed specially for production of backsheet layers, providing clear advantages over PET backsheets. Borealis makes these PP compounds available to the market by partnering with selected backsheet producers.
Standard PP grades will not pass all these tests for production of backsheet layers.
The key strength of PP in comparison with PET and PA is the hydrolytic stability
|Damp Heat test||85°C, 85 % r.h. 10.000h||No delamination|
|HAST test||121°C, 100 % r.h. 250h||No delamination|
The combination of humidity & UV is harsh for PET, therefore it needs protection by fluorinated outer layers.
The Borealis PP grades do not need this extra protection. It allows backsheet produces to replace the core PET layer by a core PP layer in laminated and coated backsheets and/ or using a 3 layer co-extrusion process with Borealis PP compounds to reduce the environmental footprint of the backsheets used in Solar PV.
Quentys™ SF700CL is a Polypropylene compound designed as a core layer backsheet offering clear advantages in backsheet production
