September 4, 2025 - Borealis has announced a major investment at its production location in Schwechat, Austria. The new PP compounding line is expected to begin operations in the second half of 2026. 

Polymer compounding is the process of blending plastic resins, such as polypropylene, with additives, fiberglass, and recycled materials to create specialty compounds with tailored properties. These materials are designed for applications that require durability, heat resistance, or lightweight performance. 

Advanced PP compounds are used in a wide range of industries, including: 

• Consumer products and appliances: Durable and recyclable materials that meet a wide range of household needs. 
• Mobility: Lightweight plastics that help extend the range of electric vehicles and support upcoming EU regulations requiring more recycled content. 
• Infrastructure: Protective outer layers for steel pipes used in high-temperature oil and gas transport.   

“This is our third significant investment this year, following the expansion our energy business and the increase in capacity for our recyclable, lightweight polymer foam solutions. Over the past decade, Borealis has built strong expertise in circular solutions that meet our customers’ expectations. With more capacity, we can deliver more of the materials they need, helping them hit performance targets and move closer to their sustainability goals”, says Stefan Doboczky, Borealis CEO.
