New polyurethane rotor blade helps wind turbines last longer


Covestro has developed the fist ever large polyurethane rotor blade. These rotor blades are fabricated in a special process from a polyurethane resin and a glass fibre fabric. The use of polyurethane resin instead of conventional composites makes the blade production cycle shorter and less energy intensive. Additionally, the new material has better mechanical properties.

As a result, the wind blades become lighter, yet longer and therefore more cost-efficient than those made from conventional materials, increasing the feasibility of wind as a low-carbon energy solution.
