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 light-weight applications that demand high fire resistance, radar transparency or operation in extremely hot or cold environments.
