First DNV GL certification for a polyurethane infusion resin

Covestro, 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.

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 Center in Denmark and the Polyurethane Research Center in Leverkusen. Covestro successfully tested the resin on an industrial scale together with Saertex, a manufacturer of glass fibre and carbon fibre fabrics and Hübers, a specialist in process engineering.
