General description:
BALKORE EG is an industrial structural material produced with kiln dried balsa wood planks
glued into blocks and then cross cut sliced into panels of the desired thickness.
The end grain configuration and the honeycomb cell structure of Balsa wood gives to this
material a unique and strong bond to most resins and materials used by the composite
materials industry. The resulting sandwich structures have very high ratios of weight to
mechanical resistance properties.
The EG panels are compatible with all resins commonly used by the composite industry, has
good fire and chemical resistance properties. Depending on the final use, it is available rigid or
flexible. To reduce the resin absortion, the product can be coated with a sealant to reduce
porosity and improve bond strength.
