BALTEK® SB.50
BALTEK® SB is a core material produced from select kiln-dried balsa wood in the ‘end-grain’ configuration. 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. BALTEK® SB is an ideal core material for an extensive range of applications subjected to static or dynamic loads in service. All while being a renewable resource.
