Selected grade structural balsa

BALTEK® SB is balsa wood from controlled cultivation cut perpendicular to the grain direction. Balsa is a universal core material due to excellent styrene and chemical resistance, as well as neutral behavior in terms of temperature fluctuations. Balsa can be processed with all known resin systems and processes and has excellent laminate adhesion properties.

BALTEK® SB is an ideal, sustainable core material made from renewable resources with a very broad range of use.
