Covestro gets certified for newly developed Polyurethane Resin for Chinese Wind Energy Market

China Wind EnergyCovestro, a global leader in the field of polyurethanes, has received the important DNV GL certification in China for one of the composite components – a newly developed polyurethane resin that improves the quality of wind blades and makes their production more efficient. The company developed an innovative technology for manufacturing wind turbine rotor blades, fabricated in a special process from a polyurethane resin and a glass fiber fabric.

DNV GL, a leading international industry standard for the safety, reliability, and performance of wind turbines, is a recognition to the market entry to the wind energy industry in China. With the highest total capacity installed worldwide, China represents around 43 percent of new installations in the global wind energy industry in 2016.

“Now we obtained the second certification for serving Chinese wind blade manufacturers,” says Kim Klausen, global head of Covestro´s wind energy program. “This brings us a big step closer to our goal of increasing the efficiency of wind power generation.”

With optimized blade design and excellent mechanical properties of the polyurethane resin, wind blades will be lighter and longer. The productivity will increase significantly with faster curing processes and improved processing properties compared to epoxy resins. These will offer new opportunities to the wind industry. Covestro, the inventor of polyurethane chemistry, celebrates the 80th anniversary since the patent registration.

Covestro collaborates with partners along the value chain to offer a high-performance resin. With strong R&D investments, a global production network and this newly acquired DNV GL certification, Covestro is the frontrunner in addressing the wind energy industry with PU solutions. With 2016 sales of EUR 11.9 billion, Covestro is among the world’s largest polymer companies.
