3M™ Balsa Panels are made of 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. The balsa panels end grain orientation gives it exceptional compression and shear properties. As an added benefit, panels providing good thermal and acoustic insulation. Balsa panels are available in 9.5 lb/ft3 density.Information provided by 3M |
