BALTEK® SBC is our balsa wood core material from controlled cultivation from 3A Composites Core Materials plantations. 3A Composites manages several thousand hectares of FSC®-certified balsa plantations. The Forest Stewardship Council (FSC®) certification acts as a catalyst for improving standards in forest management. It brings economic and social benefits to workers and local people and facilitates environmental benefits for biodiversity and the ecosystem. For BALTEK® SBC, all production steps are subjected to stringent monitoring, especially offering a physical validation for time to kiln (T2K). This monitoring process guarantees the highest-quality balsa core and full traceability from the end product back to the tree.
SBC has excellent stiffness-to-weight ratio. It can be processed with all known resin systems and processes and has excellent laminate adhesion properties. Furthermore, it is resistant to temperature changes, fire, and chemicals (e.g., styrene).
BALTEK® SBC is an ideal core material made from renewable resources with an extensive range of use.- Product Highlights
