Material Notes:
AIREX® C70 is a closed cell, crosslinked 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. A 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 lightweight sandwich structures subjected to both static and dynamic loads.Characteristicsoutstanding strength and stiffness to weight ratiosGood impact strengthLow resin absorptionHigh fatigue resistanceGood fire performance (self-extinguishing)Sound and thermal insulationGood styrene resistanceApplicationsMarine: Hulls, decks, bulkheads, superstructures, interiorsRoad and Rail: Roof panels, interiors, floors, doors, partition walls, side skirts, front-endsAircraft: Interiors, radomes, galley carts, general aviation (fuselage and wing)Recreation: Skis, snowboards, surfboards, wakeboards, canoes, kayaksIndustrial: Tooling, tanks, ductwork, containers, covers
