Diab selects SABIC’s new LNP™ COLORCOMP™ compound to enhance foams for the core of wind turbine blades
Diab Group chose SABIC’s new LNP™ COLORCOMP™ compound using nano technology to reduce weight and improve mechanical properties of sandwich structures with polyethylene terephthalate (PET) foams, which are used as the core material of wind turbine blades.
(firmenpresse) - Diab Group, a world leader in sandwich composite solutions, chose SABIC’s new LNP™ COLORCOMP™ compound using nano technology to reduce weight and improve mechanical properties of sandwich structures with polyethylene terephthalate (PET) foams, which are used as the core material of wind turbine blades. The Swedish converter selected the breakthrough SABIC compound over standard nucleators for production of its Divinycell PY PET foam core series. By reducing the foam’s cell size by a factor of up to two, while maintaining the same density and decreasing the cell size dispersity, LNP COLORCOMP compound helps enable the final part to be lighter and more efficient in use. These improvements to the core foam material can help designers create new, longer blades that address increasingly stringent standards for precision, weight and consistent quality, and contribute to greater overall energy generation.
“Even though PET foam is relatively new to the wind turbine core materials market, as a thermoplastic it offers many advantages and is a good candidate for broader use in turbine blades,” said Magdalena Sandström, CTO Diab Group. “We are focused on optimizing the performance of our PET foams to drive industry adoption of a more sustainable solution. SABIC’s new LNP COLORCOMP compound, a material that provides increased control over cell nucleation and growth, is helping us achieve this goal. By leveraging this unique technology, we are developing innovative products that enable the implementation of larger and more-powerful blades.”
“Our collaboration with Diab has opened exciting new opportunities to advance wind energy through higher-performing core materials that enable innovative composite designs,” said Luc Govaerts, director, Formulation & Application Development for SABIC’s Specialties Business. “Our novel compound based on nano technology, together with our formulation and material science expertise, help Diab to innovate, and will give wind turbine manufacturers access to core composite products that are strong, light and recyclable. Working with our customers, SABIC continues to do all we can to promote sustainability efforts across the spectrum, including supporting broader use of renewable energy sources.”
Addressing Wind Energy Challenges
The market for wind power is expected to grow at a CAGR of approximately 7.9 percent between 2020 and 2025, according to Mordor Intelligence. To support this growth, wind turbine blade designs have increased in size and efficiency to boost energy generating capacity. In Europe, the average length of onshore wind turbine blades is 50 meters (164 feet). In the United States, blades also average 50 meters, but their length is increasing, with some blades measuring up to 80 meters (262 feet). Larger blades demand new designs and improved core materials.
Another challenge is extending the useful lifespan of wind turbines to amortize their capital cost. Thermoplastic materials, such as Diab’s PET foam, deliver strength, stiffness, durability and design freedom that can help increase blade life.
Also, thermoplastics can help improve the sustainability of wind turbine blades. There are growing concerns about how to recycle these massive, complex parts, most of which are currently landfilled. Using thermoplastic PET foams make turbine blades easier to recycle. PET foam solutions offer stable supply, cost-effectiveness, and consistent material properties.
Improving Foaming Processes
SABIC’s novel LNP COLORCOMP compound features a formulation that typically provides improved nucleation and helps to enhance the efficiency of the foaming process for a wide range of foam densities. By significantly decreasing foam cell size compared to standard nucleating agents such as talc and ensuring uniform cell size distribution, the SABIC product typically helps to reduce resin uptake by the foam during composite manufacture. Less resin contributes to a lighter-weight blade.
Another potential advantage of decreased cell size is the elimination of secondary foam processes or surface treatments that are used to close foam cells and decrease resin absorption. Further, smaller cell size and narrower size distribution can potentially deliver improvements in shear strength/strain properties that are not possible with conventional technologies or lower-density foams.
Beyond wind turbine blade core materials made with PET foams, SABIC’s new LNP COLORCOMP compound typically offers the opportunity to enhance foams used in other applications, such as marine, building & construction and packaging components. SABIC’s LNP COLORCOMP compound is available globally.
