Balsa wood is the best universal core material in terms of mechanical properties, weight, and cost. However, its naturally higher resin uptake has been a weakness so far.  

BALTEK® SealX eliminates the gap between foam and balsa core for resin uptake. It reduces resin uptake by more than 80% for rigid panels and 50% for flexible panels, setting a new industry benchmark. SealX has been externally tested and approved by DNV-GL confirming resin savings and outstanding material properties.  

BALTEK® Adaptive ContourKore is a new balsa finishing option to optimize resin uptake and drapeability, thus reducing resin uptake further. With the Adaptive ContourKore 3A Composites Core Materials ends the current “one-size-fits-all strategy” that has dominated the balsa market.

“After years of joint development with lead customers, we have managed to close the gap between the foam and balsa core material with new innovative solutions, which allow our industrial customers use the unparalleled balsa properties at lowest resin uptake. Our aim is to create green products that help our customers to become more efficient and positively impact the environment” said Eric Gauthier, CEO of 3A Composites Core Materials.

The combination possibilities of BALTEK® SealX with the Adaptive ContourKore and 3A Composites’ density portfolio now allow mass customization to engineer the optimal core material system, while ensuring the lowest total cost of ownership and best performance.  

Sustainable innovation, high quality, global reach, ensured availability and close collaboration with customers drive 3A Composites to its success of becoming the leading Core Materials manufacturer.
