High Performance Structural Foam DATA SHEET 07.2011 - Replaces 02.2010DESCRIPTION AIREX® R82 is a closed-cell, thermoplastic polymer foam that combines outstanding fire resistance with very low smoke and toxicity, along with excellent dielectric properties. It has an outstanding strength to weight ratio, very low moisture absorption, is thermoformable and ductile. AIREX® R82 is an exceptional core material for use in structural lightweight applications that demand high fire resistance, radar transparency or operation in extremely hot or cold environments. CHARACTERISTICS ■ Fulfills most stringent fire requirements ■ Operating temperature from -194 °C to +160 °C (-317 °F to +320 °F) ■ Remains ductile at cryogenic temperatures ■ Excellent dielectric properties (radar outstanding transparency) ■ Very low moisture absorption ■ Good fatigue resistance ■ High impact resistance (non-brittle failure mode) ■ Thermoformable ■ Good sound and thermal insulation APPLICATIONS ■ Aircraft and Aerospace: Interiors, cockpit doors, cryogenic tanks, insulating panels, radomes, helicopter rotor blades, general aviation (fuselage and wing) ■ Road and Rail: Front-ends, side skirts, roof panels, interiors ■ Marine: Fast-ferries, fire resistant interiors, radomes ■ Defense: Naval superstructures, antennas, combat communication systems ■ Industrial: High temperature tooling, radomes, x-ray tables PROCESSING ■ Contact molding (hand/spray) ■ Adhesive bonding ■ Thermoforming ■ Pre-preg processing (up to 180 °C, 355 °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 [email protected] North America l South America Baltek Inc.
