Fire resistant foam core material for composites Alcan Airex AG
AIREX® R82/ T90

A thermoplastic foam that combines outstanding fire resistance with low smoke and toxicity, along with excellent dielectric properties. It has a high strength to weight ratio, low moisture absorption, is thermoformable, and ductile. It is an exceptional core material for use in applications that demand structural fire resistance, are required to be transparent to radar, or operate in extreme hot or cold environments.

- 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)
- very low moisture absorption
- good fatigue resistance
- high impact resistance (non-brittle failure mode)
- thermoformable
- good sound and thermal insulation
