Excellence in Core Solutions

BALTEK® SB

A core material produced from certified kiln-dried balsa wood in the 'end-grain' configuration. The properties of balsa make it ideal as a core for sandwich construction. It has extremely high strength and stiffness to weight ratios, and achieves an excellent bond with all types of resins and adhesives. It is compatible with a variety of manufacturing processes and is resistant to temperature changes, or exposure to fire, or chemicals such as styrene. It is an ideal core material for an extensive range of applications. All while being a renewable resource.
