Diab selects SABIC’s new LNP^™ COLORCOMP^™ compound to enhance foams for the core of wind turbine blades

Diab Group, a world leader in sandwich composite solutions, chose SABIC’s new LNP^™ COLORCOMP^™ compound using nano technology to reduce weight and improve mechanical properties of sandwich structures with polyethylene terephthalate (PET) foams, which are used as the core material of wind turbine blades. The Swedish converter selected the breakthrough SABIC compound over standard nucleators for production of its Divinycell PY PET foam core series. By reducing the foam’s cell size by a factor of up to two, while maintaining the same density and decreasing the cell size dispersity, LNP COLORCOMP compound helps enable the final part to be lighter and more efficient in use. These improvements to the core foam material can help designers create new, longer blades that address increasingly stringent standards for precision, weight and consistent quality, and contribute to greater overall energy generation.
