End-grain balsa is a structural core with properties that make it ideal for sandwich construction. It is compatible with all types of manufacturing processes from wet lamination to prepreg construction. Balsa is not affected by styrene or long resin gel times making it well suited for infusion applications. You can purchase rigid balsa sheets or contour cut with scrim as well as a variety of specialty cuts. Balsa is also available with a coating that minimizes resin absorption increasing bond strength and maximizing your weight savings. Today’s balsa core is available with controlled density for making more precision parts and is an economical solution to higher priced foam cores.
