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 has introduced new polypropylene based backsheet compounds for the production of solar backsheets. These compounds have been developed together with Isovoltaic Solinex in the past who sold backsheets produced with Quentys™ PP compounds under the name ICOSOLAR® CPO 3G. These compounds are now available for all customers.
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.
QUENTYSTM offers a step change in production cost efficiency for module makers while increasing power output, lifetime performance and reliability of PV modules.
