Universal Structural Foam DATA SHEET 07.2011 - Replaces 08.2010DESCRIPTION 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. CHARACTERISTICS ■ 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 APPLICATIONS ■ 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 PROCESSING ■ Contact molding (hand/spray) ■ Resin injection (RTM) ■ Adhesive bonding Europe l Middle East l India l Africa Airex AG 5643 Sins, Switzerland T +41 41 789 66 00 l F +41 41 789 66 60 corematerials@3AComposites.com North America l South America Baltek Inc.
