AIREX® C70 - Universal Structural Foam

AIREX® C70 is a closed cell, crosslinked polymer foam that combines excellent stiffness and strength to weight ratios with superior toughness.
It is non-friable, contains no CFC’s, has negligible water absorption, and provides an excellent resistance to chemicals. A fine cell structure offers an excellent bonding surface.
Compatible with most resins and manufacturing processes AIREX® C70 is ideally suited as a core material for a wide variety of lightweight sandwich structures subjected to both static and dynamic loads.
