Core material : balsa
Nida-Core Corporation

End Grain Balsa, a highly processed ultra light wood product, imparts impressive strength and stiffness to the sandwich panel. The end grain configuration of balsa provides high resistance to crushing, and is very difficult to tear apart. End grain balsa cored panels also have the ability to handle excessive dynamic loads with high resistance to fatigue. Until recently, end grain balsa was excluded from some weight sensitive applications, as there were lower density foam cores available. Now, through controlled growing and careful selection, BalsaLite balsa wood is competitive in weight, as well as offering superior performance in stiffness and strength, particularly where local crushing or bruising is a concern.

Nida-Core is a proud BalsaLite balsa wood supplier. BalsaLite is select quality, kiln-dried, end-grain balsa wood suitable as a structural core material in composite sandwich construction. BalsaLite balsa wood is a naturally renewable resource. The balsa plant (Ochroma lagopus) grows from seedling to mature balsa tree in 4-6 years and reaches heights up to 25 m (90 ft) before dying in 8-10 years. Tropical winds spread balsa seeds throughout the equatorial highlands of Ecuador where mature trees are harvested. The trees are then milled and kiln-dried. After being converted to BalsaLite, the product is supplied to Nida-Core your balsa wood supplier in the USA, Europe Mexico, France etc%u2026 and finely you. BalsaLite's end-grain orientation gives it exceptional compression and shear properties. As an added benefit, BalsaLite provides good thermal and acoustic insulation.
