Covestro, a leading global supplier of high-performance polymer materials, has delivered its first commercial order of polyurethane raw materials for wind blades to China. China is the world’s largest wind power market with 221 GW of installed capacity at the end of 2018, according to the World Wind Energy Association.(1) The blades, produced by Zhuzhou Times New Material Technology(TMT), one of the largest manufacturers of wind blades in China, have then been delivered to Envision, a leading global wind turbine technology company. They are scheduled to be installed in a wind farm in East China in July 2019.
Covestro delivered polyurethane resin to TMT for the production of 18 polyurethane wind blades of 59.5-meter-length, also for the spar caps and shear webs. These blades were delivered to Envision, heralding the successful deployment of Covestro’s innovative polyurethane resin in blades for commercial wind farm projects.
To ensure successful deployment, the Covestro wind power team produced a prototype of the wind blades which has passed static and fatigue tests. The prototype was put into trial operation at a wind farm in central China in 2018.
