Working in China with partners, the German polymer maker Covestro has created what it calls the first-ever large polyurethane rotor blade for wind turbines. The company is promoting polyurethane as an alternative to epoxy resins in making fiberglass-reinforced polymer parts. It says polyurethane flows more easily, ensures better wetting of glass fibers, and cures more quickly.
