3A Composites Core Materials AIREX® R82.60 High Performance Structural Foam
Categories:	Other Engineering Material; Composite Core Material; Polymer; Thermoplastic
Material Notes:	AIREX® R82 is a closed-cell, thermoplastic polymer foam that combines fire resistance with low smoke and toxicity, along with good dielectric properties. It has a good strength to weight ratio, very low moisture absorption, is thermoformable and ductile. AIREX® R82 is a core material for use in structural lightweight applications that demand high fire resistance, radar transparency or operation in extremely hot or cold environments. Characteristics Fulfils 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 transparent outstanding) 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
