Covestro polyurethane resin composites: an easy choice for wind turbine blades
Polyurethane resin is a cost effective and high performing rotor blade composite material
Easy PU resin flow processing makes composites cost-effective
The excellent flow properties of polyurethane infusion resin include very low viscosity, long pot-life and fast curing. This allows for better infusion in the blade composite materials used by the renewable energy industry. The PU resin technology may also enable a blade design for reduced overall weight and volume. High performing composites for rotor blades are long-lasting thanks to their enhanced mechanical properties, even in demanding conditions that wind turbines are exposed to.
An innovative machine for the production of polyurethane turbine blades
As the wind energy market requires ever-larger blades, Covestro developed a special Baulé machine for the direct infusion of high performance polyurethane into rotor blades. In cooperation with industry partners such as Goldwind, Covestro Elastomers designed a pioneer metering machine meeting challenging technical requirement such as processing under vacuum and adapting the output all along the wind blade production.
