Industrial Processing Foam DATA SHEET 02.2016 - Replaces 07.2011DESCRIPTION AIREX® C51 is a closed-cell polymer foam with outstanding damage tolerance and formability. Its excellent price / performance ratio uniquely qualifies this core material for high-volume sandwich production. The foam has a high elongation at break and shows good impact properties. It can be formed at room temperature to simple shapes as well as thermoformed to complex 3-dimensional parts. The perforation of AIREX® C51's surface ensures a good adhesion to the laminate. The elevated temperature resistance allows short processing cycles with fast curing resin systems, including thermoplastic fiber reinforced skins (GMT) making it very suitable for mass-produced lightweight sandwich structures subjected to both static and dynamic loads. CHARACTERISTICS ■ High impact resistance (non-brittle failure mode) ■ Elevated short-period temperature resistance ■ Cold and hot formable to 3-dimensional contours ■ Good fatigue resistance ■ Superior bond strength ■ Low resin absorption ■ Good sound and thermal insulation APPLICATIONS ■ Road and Rail: Car bodies, headliners, deflectors, spoilers, seats, truck panels, side skirts, covers ■ Wind energy: Turbine generator housings ■ Industrial: Containers, shelters, covers PROCESSING ■ Contact molding (hand/spray) ■ Compression molding (GMT) ■ Thermoforming ■ Infusion ■ Resin injection (RTM) ■ Adhesive bonding ■ Pre-preg processing (up to 120 °C, 250 °F) 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.
