Covestro, a globally leading supplier of high-tech polymer materials, has developed an innovative technology for manufacturing wind turbine rotor blades.

The rotor blades are fabricated in a special process from a polyurethane resin and a glass fibre fabric. The company has now received the important DNV GL certification for the resin, according to a press release.

DNV GL, an abbreviation of the companies Det Norske Veritas, and Germanischer Lloyd, which merged in 2013, is a leading international industry standard for the safety, reliability and performance of wind turbines. The Covestro system is the world's first polyurethane resin to receive this certification.

The resin was developed in a close co-operation between the Covestro Wind Competence Centre in Denmark and the Polyurethane Research Centre in Leverkusen. It has a major influence on stability and durability, the two critical properties of rotor blades.

Covestro successfully tested the polyurethane resin on an industrial scale together with Saertex, a leading manufacturer of glass fibre and carbon fibre fabrics, and HÜBERS, a specialist in process engineering. (GK)
