AIREX®R82
Product Details
DESCRIPTION
AIREX® R82 is a closed-cell, thermoplastic polymer foam that combines outstanding fire resistance with very low smoke and toxicity, along withexcellent dielectric properties.It has an outstanding strength to weight ratio, very low moistureabsorption, is thermoformable and ductile.
AIREX® R82 is an exceptional core material for use in structural lightweight applications that demand high fireresistance, 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
