SteloraTM

How it works

The result of an exclusive collaboration between Borealis and TOPAS Advanced Polymers, Stelora is created using a unique process that combines cyclic olefin copolymers (COCs) with polypropylene (PP). The resulting state-of-the-art ethylene-propylene-norbornene (EPN) material solution is suitable for a wide range of technically advanced applications, primarily used in e-mobility and renewable energy generation

Why Stelora?

Stelora solutions replace existing engineering polymers in a wide range of applications, offering enhanced performance in multiple categories:

• Very high purity for exceptional performance and durability

• A step change in heat resistance, closing the gap between conventional polymers and high-temperature plastics

• Excellent processability using existing equipment, infrastructure and assets

• Superior electrical properties at high temperatures

• Increased efficiency

Supporting the Green Energy Transition

The green energy transition is critical to efforts to avert the worst effects of the climate crisis. This shift, from fossil fuels to renewable energy, is key to both the UN Sustainable Development Goals and the European Green Deal.

At Borealis, we’re committed to supporting these efforts, so we’re continually innovating to create the next generation of sustainable solutions.

A new class of engineering polymer, Stelora will unlock progress for the renewable energy sector, lowering costs, and increasing efficiency.

A circular way

Our vision is a world in which high-quality plastic products are kept in circulation in an eco-efficient way – a circular way.

We’re committed to leading this change, supporting our customers to realise their sustainability ambitions by transforming the plastics life cycle.

With Stelora, we mark another step on this journey: this unique EPN solution is produced using renewable feedstock, creating value out of waste and helping to build a brighter future for our planet.

High-performance applications

High-heat-resistant capacitor films

The first commercially available application of Stelora technology is a resin suitable for a range of high-heat-resistant capacitor film. This dielectric capacitor film offers all of the benefits of that made using PP film, but with significant performance enhancements including exceptional heat resistance, superior electrical properties at high temperatures, and increased efficiency. Stelora-based film is also fully compatible with existing converting lines, so that you can process it without needing to invest in new equipment, infrastructure or assets.

Benefits of increased heat resistance:

• Power Generators

Reduced degradation extends the lifespan of power generators, including offshore wind installations

• Transformer Substations

Less space is required for cooling, reducing the size and construction cost of transformer substations

• Electric Vehicles
• Smaller and more energy-efficient final products that use transmitted energy can be produced, including electric vehicles.

EPN is produced using renewable feedstock.
