ICORE Balsa Core – 1/2", 3/4", 1" & 2"

ICORE Balsa Core is a high-performance end-grain balsa core material offering an excellent balance of strength, stiffness, and low weight for structural composite applications. Manufactured from carefully selected balsa wood, it delivers outstanding compressive strength, shear properties, and long-term durability in demanding environments.

The end-grain construction provides superior load distribution, high fatigue resistance, and excellent impact performance, making it well suited for areas subjected to high static and dynamic loads. ICORE Balsa Core also offers reliable processing characteristics with controlled resin absorption for consistent laminate quality.

Available in 1/2", 3/4", 1", and 2" thicknesses, ICORE Balsa Core is compatible with a wide range of composite manufacturing methods.
