    Leverkusen, Germany – The collaboration between Covestro and Zhuzhou Times New Material Technology (TMT) has produced its 1,000th wind turbine blade. This represents rapid progress for a collaboration signed a year ago.

    The turbines produced by TMT are being used in commercial wind farms China. The country’s current five-year plan aims to double wind and solar power output by 2025.

    PU resin is increasingly being used in place of fibreglass-reinforced epoxy in the manufacture of turbine blades. Covestro says this is because it has better mechanical properties and a more efficient and cost-effective production process.

    The PU wind blades made by TMT range from 59.5m to 94m long, with a variety of different blade designs and lay-up structures. The longest blades can generate 8MW of energy.

    "PU wind blades cater to the growing demand for longer wind blade designs," said Binbin Hou, general manager of TMT’s wind business. "We hope to further collaborate with Covestro to improve the competitiveness of wind energy through continuous technology innovation."

    "We believe that industrial collaboration is fundamental to addressing global warming and energy shortage issues," said Christine Bryant, head of Covestro’s tailored urethanes business. "It is also an important part of Covestro’s commitment to a circular economy."
