BALTEK® SB balsa wood from controlled cultivation; it is cut perpendicular to the grain direction. Balsa is a universal core material due to the excellent styrene and chemical resistance as well as the neutral behavior in terms of temperature fluctuations. Balsa can be processed with all known resin systems and processes and has excellent laminate adhesion properties.
Reduces resin absorbed by core in VARTM (infusion) by up to 90% in rigid sheets and 50% in contourable (CK) core.
- No change to laminate design values (same strength).
- Compatible with polyester, vinylester and epoxy.
