AIREX
C70 is a closed cell, cross-linked polymer foam that combines
excellent stiffness and strength to weight ratios with superior toughness.
It is non-friable, contains no CFC s, has negligible water absorption, and
provides an excellent resistance to chemicals. The fine cell structure
offers an excellent bonding surface.
Compatible with most resins and manufacturing processes AIREX
C70 is ideally suited as a core material for a
wide variety of sandwich structures subjected to both static and dynamic loads. Thanks to its unique lightness
(properties vs. density) C70 is the material of choice for applications where lightweight is a priority.
Outstanding strength and stiffness to weight ratios
Good impact strength
Low resin absorption
High fatigue resistance
Good fire performance (self-extinguishing)
High sound and thermal insulation
Good styrene resistance
Marine: Hulls, decks, bulkheads, superstructures, interiors
Road and Rail: Roof panels, interiors, floors, doors, partition walls, side skirts, front-ends
Wind energy: Rotor blades, nacelles, turbine generator housings
Aircraft and Aerospace: Interiors, radomes, galley carts, general aviation (fuselage and wing)
Recreation: Skis, snowboards, surfboards, wakeboards, canoes, kayaks
Industrial: Tooling, tanks, ductwork, containers, covers

ProBalsa is a high quality organic core material made from end
grain balsa wood. The end grain, micro honeycomb structure offers
exceptional shear and compressive strength. In addition ProBalsa
offers good fatigue properties, high thermal and sound insulation and
low FST (fire, smoke & toxicity) properties. ProBalsa is best suited for
dynamic structures where performance and efficiency are important.
All ProBalsa core materials are particularly easy to work using
conventional woodworking tools. It can be drilled, milled, turned
and sawn to close tolerances. ProBalsa is compatible with most
resin and manufacturing processes. It is also suitable for elevated
temperature cure prepreg systems.
