Borstar® is Borealis' state-of-the-art multi-modal proprietary technology for manufacturing polyethylene and polypropylene
Borstar® is Borealis' state-of-the-art multi-modal proprietary technology for manufacturing polyethylene (PE) and polypropylene (PP). Combined with Borealis' unique catalyst technology, Borstar supports the production of a wide range of enhanced PE and PP products for the most demanding applications by enabling molecular design. The Borstar process offers simultaneous improvements in conversion economics and in key environmental aspects, such as energy efficiency and raw material recycling.
Borealis provides continued Borstar development and is further commercialising the next generation of Borstar such as Borstar PE 3G. The new developments represent a leap forward in process technology, allowing flexible polymer design from bi-modal to multi-modal PE/PP resins and facilitating the development of an ever-widening range of new plastics that outperform alternative materials in meeting the needs of manufacturers and end users.
Global growth through Borstar PE and PP capability and capacity expansion is a core ingredient of the Borealis strategy. Significant growth projects include Borouge, the joint venture with the Abu Dhabi National Oil Company (ADNOC) in the United Arab Emirates and Bayport Polymers LLC (Baystar™), the 50/50 joint venture owned by TotalEnergies and Borealis in North America. Following the successful start-up of the Borouge 3 project in 2016, the site in Ruwais is now the world’s largest integrated polyolefins complex, with a production capacity of 4.5 million tonnes and aiming at further growth. Baystar includes a 625,000 metric tonne-per-year Borstar polyethylene unit at its production site in Pasadena, Texas, and a one-million-tonne per year steam cracker in Port Arthur, Texas. The new cracker processes ethane and will supply feedstock for its existing 400,000-ton-per-year polyethylene units as well as the new unit in Pasadena.
The cornerstone of the Borstar technology is delivering innovative products through its efficient and flexible design. Borstar's key components are proprietary polyolefin multimodal process technology and proprietary catalyst systems.
The Borstar multimodal polymerisation process enables tailor-made polymer materials for demanding applications via:
This makes it possible to create more sophisticated, customer-oriented solutions characterised by a unique property combination.
Borstar delivers what its customers need - consistently superior property products that can be converted into applications, which give sustainable value. The Borstar process provides innovative polymers with both good mechanical properties and good processability in a broad range of product applications (e.g. automotive, pipe, packaging, etc.) at competitive cost and improved environmental sustainability (e.g. downgauging).
Borstar materials feature, depending on the application, a number of special property and structural benefits, which are realised from tailoring the resin's molecular structure in both the Borstar PE and Borstar PP process. These include:
