SABIC introduced LNP COLORCOMP WQ117945 compound, a material based on nanotechnology that facilitates efficient production of polyethylene terephthalate (PET) foams for core materials in sandwich structures. This new compound improves control over nucleation and cell growth, resulting in decreased cell size and uniform, narrower cell size distribution. These attributes can reduce the foam’s weight by minimizing resin uptake in sandwich structures. It can also potentially improve shear strength/strain properties for better fatigue performance. Enhancing PET foams with SABIC’s new LNP COLORCOMP compound can address the evolving needs of multiple industries, including marine, building and construction, packaging, and wind energy. SABIC’s LNP COLORCOMP WQ117945 compound can significantly reduce foam cell size, while decreasing cell size disparity by a factor of up to five. These factors help to reduce resin uptake by the foam during composite manufacture, resulting in a lighter-weight wind blade. PET foams offer versatility in the design and shaping of wind blades, and also offer stable supply, cost-effectiveness, consistent material properties and much less resin uptake.
